If you take a look at the people you keep inviting into your life — friends, partners, coworkers, landlords — and notice an unusually large number of them are selfish, cruel, chaotic, or otherwise harmful, there’s a good chance your alarm system for danger is malfunctioning. That internal red-flag sensor is meant to warn you when someone unreliable or harmful is approaching, whether that’s a romantic partner, an employer, or a living situation. When it’s working, you feel unease, reluctance, or a clear “no” about people and circumstances that drain you. What turns that crucial mechanism off for many of us is childhood abuse and neglect. These early wounds are not your fault, but healing your ability to detect danger is now your responsibility — and it must become a priority. So long as hurtful people can enter your life and your heart, you remain at risk of repeating old, painful patterns you have tried so hard to outgrow.
Why does this happen, and how do you repair it? Consider the high price of lacking any filter for who you allow in: the seats reserved for people who genuinely love and support you get occupied by people who are emotionally distant, exploitative, or incapable of care. Sometimes they outright use you. At other times they simply take up the space where dependable people should be, leaving you without the stable support everyone needs. If your detector is broken, your life can fill with very damaged people who will, in the end, leave you more hurt than you started. Everything worthwhile — safety, steady love, trustworthy relationships — depends on shutting the door on destructive people so there’s room for people who will actually sustain you.
I speak from experience: for years I ignored red flags as if blind to them. The process can feel like a runaway train: it begins slowly, gains momentum, and doesn’t stop by itself. The more toxic people you allow in, the more your boundaries unravel; then worse people enter, each relationship draining a little more of you. If you hope to heal and be happy, you must relearn how to quickly spot those who are not good for you — but you can’t do that while your detector is impaired. The good news is that you can restore it, and I’ll explain how.
Red flags are the clues unhealthy people give off, signals that someone is unsafe, not who they pretend to be, or emotionally unavailable. Sometimes they state these clues plainly: in dating, a direct “I’m not looking for a relationship” is a bright flashing warning. Have you ever ignored such a line, telling yourself you can change them? The cost of that hope can be devastating. Some people conceal their true intentions until after sexual intimacy, at which point you find yourself trapped in the awful choice of confronting them or pretending you didn’t expect commitment either. That is manipulative: they weren’t available and they deliberately delayed telling you until it served them. Believing you can somehow convert them — trusting that your goodness will eventually win them over — is a distortion that complex trauma (CPTSD) can create. Trauma doesn’t only warp thinking; it can obscure what you hear and see in plain sight.
Other warnings are less obvious and require careful listening and testing. Emotionally attuned, healthy people notice subtle signs and respond accordingly; they rarely allow manipulative, dishonest, or unavailable people into close quarters because they can sense trouble from afar. Abuse and childhood neglect frequently damage that subtle perception. We lose the habit of accurately reading small cues and become easily ensnared, struggling to disentangle ourselves. Maybe you’ve been excited about someone new, yet people who love you give a puzzled look as if to say, “What are you thinking?” That’s their detector functioning while yours is offline. Ironically, with CPTSD you can be good at “unseeing”: you notice something, then you forget you ever noticed it. You might blank in the moment and later can’t recall why you swore you’d never repeat a certain mistake. Your memory of why a choice was dangerous becomes inaccessible; suddenly you convince yourself the risky situation is fine, and that lapse — that sudden black hole of awareness — is what leads to repeated missteps.
Why would anyone act against their own interest so often? Several trauma-related reasons explain it. First, childhood trauma can cause brain changes that make denial-like shutdowns a neurological response rather than a character flaw. Abuse and neglect impair the ability to process and retain stressful information; when confronted with emotionally charged choices, higher-level thinking can falter or switch off entirely, leaving decisions to impulses and heartache. People without severe trauma often find this unimaginable, but those who’ve lived through it know the feeling of waking up and wondering how they made the same mistake again. It’s not simply denial; it’s a physiological coping strategy learned in childhood.
When children are exposed to chronic chaos — parents fighting, substance use, violence, or repeated lies coupled with unrealistic reassurances that “everything’s fine” — they learn survival strategies that blunt their instincts. Turning off perception and gut feelings becomes a habit that is later hard to undo. You may have trained yourself to override natural alarms, numbing out in the face of fear and confusion. That numbness may look like being composed or appearing “okay,” but it’s not the courageous kind of vulnerability that lets you feel, assess, and react. This kind of protective numbing helped you survive as a child; it shielded your spirit when you had no power to change what was happening. Part of healing is reclaiming the parts of yourself you put away for safekeeping until it became safe to bring them back. Without that recovery, going numb in adult life means you won’t notice danger signals when someone harmful arrives, or a desperate longing for connection may drown out the alarm that says “run.”
Another trauma outcome that impairs detection is dysregulation. Many trauma survivors have nervous systems that go out of sync quickly: triggers can rapidly shift brain activity from calm, coordinated patterns to jagged, chaotic states. When dysregulated, your senses and thinking become unreliable; emotions either erupt in overwhelming outbursts that push others away, or they collapse into numbness. That’s why your red-flag detector can get stuck: you end up in relationships with people you’d normally be repelled by, frozen like a deer in headlights, marching toward the next crisis. Dysregulation can make you unable to sequence thoughts, act decisively, or use your hands to extract yourself from danger — for example, failing to get out of a car driven recklessly by an angry person because you were too overwhelmed to respond. If you want help healing dysregulation, there are resources and practices that can assist — look for trauma-informed supports and therapeutic approaches that teach nervous-system regulation.
Manipulative people can also pressure you to ignore your instincts by using language that shames or dares you — calling you “closed off,” “prudish,” or “chicken,” insisting you must be “in the moment” or “open up.” If you lacked firm boundaries and were raised to deny your reality, it’s easy to abandon your sensible instinct simply because someone coerced you. That can leave you isolated, vulnerable, and endangered. Another common pattern among trauma survivors is chronic self-doubt: you end up second-guessing yourself constantly. If you grew up abused or neglected, you likely replay scenarios mentally, wondering if someone actually threatened you, or whether you’re “imagining” it. You might spend an enormous amount of energy trying to decide whether someone is mistreating you, or whether you somehow deserve it. Imagine how different life would be if you could reliably distinguish between true danger and merely anxious intrusions — that’s one of the gifts of trauma recovery: learning to tell the difference between realistic red flags and paranoid fears.
The most frequent reason people with CPTSD tolerate harmful partners is unmet, desperate need. That hunger for connection can be so deep that you’ll put up with a lot just to have someone with you. If that resonates — if you ever settle for a bad companion because the ache of loneliness is unbearable — pay attention. That awareness is the first step toward restoring your ability to recognize and avoid danger. Here are four steps to begin repairing your red-flag detector.
1) Get clear. Write it down. Be explicit about the traits and behaviors that indicate someone is not a good fit for your life. In my relationship course, the first lesson is always to get absolutely clear about what you want and what you won’t tolerate. For reviving your detector, go further: list specific characteristics that would actively harm you or jeopardize your children — abusive behavior, criminal activity, addiction, alcoholic behavior, unreliability, severe untreated mental illness, emotional unavailability, or inappropriate entanglements (e.g., a boss, a professor, or a married person). Once you’ve spelled out what you don’t want, ask yourself how you’ll actually spot those traits early on. People who hide dangerous traits may not show them on the first date, but they often reveal subtler signs: how they treat servers, animals, or other people. Addiction can be hidden, but with time and distance it also signals itself. Getting to know someone requires time, and crucially, time when you’re not already bonded to them.
2) Slow things down. If your detector is rusty, rushing is a trap: taking things slowly gives you space to stay present while you gather evidence. That means resisting the urge to accelerate intimacy, the fantasy-making of a new person into your soulmate, or rushing to cohabit. Think of it as practicing a developmental skill you missed out on. If going slow is difficult, recruit a trusted friend to be your sounding board. Recovery from delusion can feel like being swept down a current; a friend standing on the bank can help pull you out. Tell them your plan to take it slow and share the clear list you made of what you want and what you never want again. If you’ve been secretive about your worries in past relationships, commit to transparency with your accountability person; shine sunlight on the sticky areas of your life.
3) Create a sustainable daily practice. Change generates fear, resentment, and intrusive thoughts that cloud judgment. To keep moving forward when things get uncomfortable, use daily practices that clear fearful or resentful thinking. Trauma often creates a blind spot where discernment should be, leaving you vulnerable to people who lie or misrepresent themselves. That blind spot is how so many end up heartbroken, ghosted, or disappointed; someone who was telegraphing their true nature from the start can still blindside you if you’re not tuned in. Daily habits that help regulate mood, reduce hypervigilance and teach awareness will support clear thinking and better decisions.
To illustrate these patterns and how to respond, consider some letters I received. One is from a woman I’ll call Jamila. She says she often enters relationships that end when the honeymoon phase is over. In her latest attempt to change, she met a 37-year-old man on a dating app. They never married before, she reports a strong chemistry, and he was taking things slowly — which felt like a relief compared with previous love-bombing. But he remained secretive: he refused to give his last name after two months of talking and would not explain past failed relationships. After two months of messaging, he flew to meet her; the date seemed fine, yet when she hugged him as they parted, she felt him recoil. A few days later, when she asked about their status, he panicked and insisted she shouldn’t ask; “men should initiate,” he said. From there the communication frayed: he went back to his country for a work trip, and then his contact became sporadic. Excuses piled up — a father in hospital, other crises — and Jamila began to suspect he was seeing someone else. Two months of vague disappearances ended when she saw a woman newly following him on social media. When she sought clarification, he ghosted her. She blocked him but is devastated and confused, feeling doomed to keep choosing the wrong people.
Jamila actually has good instincts. Her man’s behaviour — secrecy about his family name, evasiveness about relationship history, sudden disappearance, and social-media evidence of another woman — is textbook red-flag material. There’s a real possibility he was never available or was juggling other relationships. Even if he later offered romantic words online after he returned, that’s often the behavior of someone keeping their options open. Jamila’s request for clarity was reasonable; his panicked avoidance when asked about commitment and his secretive moves (not sharing a last name, not being searchable) are significant warning signs. If someone truly cares, they want to reduce your doubt, not cultivate it. When people ghost instead of directly ending things, it shows a lack of courage and accountability that will sabotage any long-term partnership. The takeaway for Jamila — and anyone in a similar situation — is to trust that gut unease, insist on clarity early, and accept that going slow and asking direct questions is entirely appropriate. If your goal is a committed relationship, state that upfront: anyone unwilling to engage in a frank conversation about relationship goals is not someone to invest in.
Another letter came from a man I’ll call David. He’s 33 and proposed to his 32-year-old girlfriend after little more than a year together and living together, but he now worries the relationship is crumbling. His girlfriend had a tough childhood — emotionally absent and manipulative father, overly enmeshed mother — and she struggles to show emotions and love; she described a pattern of clinging to unavailable figures. Early in their relationship she introduced him to a man she’d called a father figure, and David later discovered she had sexual and romantic involvement with that man when he visited the country. The man has a wife and kids; she had ongoing contact with him, including sexting, and kept the relationship hidden. David confronted her, set a boundary — it’s him or the other man — and she chose him, but she continued to find ways to maintain contact and resent his demand. After she cut off the contact, she became depressed; sex dwindled and arguments became frequent. They went to couples therapy; the counselor acknowledged her childhood trauma was affecting their relationship. She fears David because of his size, interprets normal questions as snooping, and sometimes has tantrums, leaving him feeling exhausted. David asks whether he should try to stay, fix things, and help her heal.
The core issue in David’s case is boundary enforcement and readiness for a committed tie. He’s tried to set boundaries about an intimate third party, but her ongoing secretive contact and resistance to truly letting go showed him she was not fully invested in him — or that she couldn’t give up a clandestine connection that made her feel safe in a dysfunctional way. Trauma can explain why someone clings to emotionally unavailable partners; it doesn’t excuse deceit or the refusal to respect a partner’s clear boundary. In a healthy partnership, when a boundary you set is repeatedly ignored or walked around, that’s a signal something fundamental is not aligned. Proposing marriage while trust remains fractured and secrecy remains in play is premature. Counseling can help, but if the behaviors persist and you’re the one continuously accommodating and compromising your needs, pause the wedding plans. Being compassionate about a partner’s past is one thing; tolerating ongoing secretive intimacy with someone else, and the erosion of basic safety and trust, is another. Protect your standards and be honest about whether the relationship really feels stable and fair in practice, not only in theory.
The third letter is from Phoebe, whose story is heartbreaking and complex. She describes a childhood in which her mother — possibly personality-disordered, emotionally absent, and manipulative — created a chaotic family environment. Her grandparents largely raised her while her mother made poor choices and blamed Phoebe for leaving home at 16. Phoebe later cared for her grandfather and experienced rewarding, healing moments with him, only to be betrayed when her mother coaxed her and her then-partner to move into Grandpa’s house, then disappeared while exploiting the situation and leaving Phoebe to manage his needs. This prolonged stress triggered physical symptoms (alopecia), and it took years for Phoebe to recognize her mother’s likely personality disorder. She then found herself repeatedly attracting partners who mirrored her mother’s traits.
One of those partners — “Leo” — began as intense love, then rapidly moved in, became controlling, isolated her from work and friends, and escalated to violence, finally perpetrating sexual betrayal (secret videos) and chronic deceit (faking an Irish accent, lying about his family and history). He drained her savings, left her homeless and broken when she finally escaped with help from friends and a domestic-violence center. Phoebe now struggles with trauma bonding, CPTSD, dissociation, depression, insomnia, nightmares, and intense fear of trusting again. She’s getting free therapy through a shelter but is overwhelmed, grieving both the relationship and the life she lost.
Phoebe’s story exemplifies how childhood trauma shapes adult attraction patterns: we subconsciously gravitate toward familiar dynamics, even when those dynamics are damaging. Her survival instincts helped her endure abuse early on, and later she coped by attaching to people who replayed those dynamics. Now she’s caught in the painful aftermath — financial loss, betrayal, and a trauma storm. Recovery begins with safety and connection. Reaching a domestic-violence shelter was a wise, courageous step; those services know how to navigate the practical and psychological fallout. The financial loss, though devastating, can be rebuilt; the safety and healing of your life are invaluable. For immediate crises of activation (“trauma storms”), prioritize basic self-care: sleep, hydration, limited alcohol, nutritious meals (less sugar, more protein), sunlight, movement, and social connection. Physical activity and outdoor time stabilize the nervous system. Therapeutic tools like EMDR (Eye Movement Desensitization and Reprocessing) can help process intense memories and reduce the ongoing reactivation of trauma; many survivors find EMDR moves traumatic memories into a less triggering place very efficiently. Keep engaging with supportive therapy, community, and friends who helped you escape. Your trauma bond is powerful, but bonds loosen over time with consistent separation and care.
Across these stories, several consistent themes recur: trauma rewires perception and response, making it hard to notice or act on danger signals; secrecy, avoidance, and gaslighting are common tactics used by people who are unsafe; healing requires clarity, slow knowing, trusted feedback, and deliberate practices to regulate emotions and cognition. You can learn to tell the difference between justified alarm and misplaced suspicion; you can rebuild boundaries that actually mean something and stop tolerating what hurts you. Over time you’ll re-develop the radar you needed all along, so that when someone is dishonest or emotionally absent you can see it, trust your perception, and act in your best interest.
If you are in the middle of these struggles right now, remember: progress is rarely linear. You may make steps forward and then fall back; that’s normal. Healing looks like gradually asserting clearer boundaries, learning to bring things out into the light with trusted people, and creating consistent daily practices that clear fear and resentment and strengthen discernment. For those tempted to rush into solutions, be patient: slow, deliberate change is the path to a durable detector that warns you before someone damaging gets too close. Over time, with support and practice, the fog lifts, impulses become clearer signals, and your life opens up to people who genuinely belong in it. You can learn to trust your senses again, to protect your heart, and to make room for love that is steady, honest, and safe.
