Why Do I Keep Going Back to Someone I Know Is Bad for Me?

Many of you already know the relationship is bad for you. That's not the question. The question keeping you up at 2 a.m. is why knowing that hasn't been enough to make you leave.

This is the question I hear more than any other in my work with survivors of narcissistic and abusive relationships- usually followed by "what's wrong with me." Nothing is wrong with you. Here's a hill I will die on as a narcissistic abuse therapist: knowing a relationship is harmful and being able to leave it are two different jobs for two different systems-  one cognitive, one emotional and nervous-system based- and insight in the first doesn't transfer to capacity in the second. That gap isn't a character flaw. It's the mechanism.

I’m Chelli Pumphrey, MA, LPC. I've spent the last 35 years treating survivors of narcissistic abuse, and I'm also a survivor. What's happening to you has a name and a distinct pattern, and once you see it clearly, the pull loosens its grip- just from simply being named.

Key Takeaways

• Going back to an abusive partner isn't a willpower failure. It's the predictable result of a trauma bond, backed by decades of research on abusive relationships.

• The pull is strongest because the relationship was unpredictable, not despite it.

• Trauma bond withdrawal is extremely painful and confusing, and can even come with physical symptoms such as insomnia, panic attacks, low appetite, among others. 

• Certain narcissistic abuse tactics, such as gaslighting, are engineered to make leaving harder, whether the person doing them realizes it or not.

• Breaking a trauma bond takes distance, a plan for the urge before it hits, and support in the form of trauma therapy specific to narcissistic abuse and intimate partner violence.
  

What's Actually Happening: The Trauma Bond

A trauma bond is a real attachment, formed through cycles of affection and harm delivered on an unpredictable schedule. It's not a formal clinical diagnosis, but it's one of the most consistent patterns we see in survivors of narcissistic and abusive relationships, and it's backed by research, not just observation.

Here's the distinction I make with almost every client who asks this question: healthy love gets calmer the longer you're in it. A trauma bond gets more intense the more chaotic things get. That's backwards from how secure attachment works- and that backwardness is the diagnostic clue.

The mechanism behind it is intermittent reinforcement, the same principle that keeps a slot machine profitable. Unpredictable reward is a stronger behavioral hook than consistent reward, full stop. If the person had been reliably unkind, you'd have left months ago. It's the love bombing returning unpredictably after devaluation that keeps the system engaged.

That cycle also produces cognitive dissonance: "they love me" and "they hurt me," held at the same time, in the same nervous system. This isn't just exhausting to live inside. Research on trauma bonds has found that this dissonance measurably impairs executive functioning- decision-making, reasoning, memory, planning- and can trigger a freeze response, where you become unable to act because you can't resolve who your partner actually is. It's a documented reason survivors leave an average of seven times before the relationship ends for good. Seven. If that number sounds familiar, that's your red flag, and it's a bright one.

People often ask if this is just codependency. It's related, but treating them as the same thing or treating codependency as the root problem misses what's actually happening. Codependency isn't a personality flaw to fix on its own; it's usually a trauma response itself: fawning, freezing, appeasing- your nervous system doing what once kept you safe. That's why naming the pattern rarely breaks it on its own; the trauma underneath it hasn't been touched. and that's exactly where trauma therapy for narcissistic abuse comes in. A trauma bond runs on top of that, with its own specific hook: not fear of being alone, but the not-knowing, built by intermittent reinforcement. The two often travel together, and survivors with high agreeableness and conscientiousness personality traits are especially vulnerable to both- not because something is wrong with them, but because forgiving, trusting, and seeing the good in someone are exactly the traits a trauma bond exploits.

Love	Yes	Consistent safety
Codependency	No	Fear of abandonment
Trauma bond	No (feels more chaotic)	Unpredictability itself

The Research Behind It (This Isn't Pop Psychology)

Donald Dutton and Susan Painter weren't writing self-help content in 1981 when they proposed traumatic bonding theory. They were trying to name something clinicians kept observing and couldn't yet explain: survivors forming stronger attachments to partners who treated them worse, not better.

A follow-up study published in the journal Violence and Victims tracked 75 women after they'd left abusive relationships. The finding: the more inconsistent the abuse had been, the stronger the lingering attachment, measured months after the relationship had ended.

One detail gets buried too often in how this research gets cited: the same study found that attachment dropped by roughly 27% within six months of no contact. That's worth noting. It means the pull is strongest early and it does loosen, but with distance and time, not with willpower alone.

Think about a slot machine versus a vending machine. The vending machine gives you the same soda every time; nobody gets emotionally attached to a vending machine. A slot machine pays out unpredictably, and unpredictability is exactly what keeps a hand on the lever. Swap the coins for affection. Your nervous system doesn't know the difference.

Why You Miss Someone Who Hurt You

Here's the quiet part, said out loud: missing someone who hurt you doesn't mean the relationship was secretly fine, and it doesn't mean you're confused about what happened. It means your brain paired relief and connection with a specific person, over and over, through the same intermittent reinforcement that built the bond in the first place. That pairing doesn't check whether the person deserved it.

Trauma bond withdrawal describes what shows up once you actually create distance: insomnia, a knot in the chest, checking the phone on a loop, appetite gone or doubled, panic waves with no obvious trigger attached.

Some of this overlaps with hypervigilance- the sense of being on alert even when nothing in the room is actually threatening you right now. It's a leftover setting your nervous system hasn't updated yet, not a personality trait.

This isn't you falling apart. It's closer to what someone experiences after addiction: the body hasn't caught up with a decision the mind has already made. Knowing that in advance keeps you from mistaking a withdrawal wave for proof you made the wrong call.

I'll be honest: this is where a lot of people quietly talk themselves out of what they're feeling. "It's just heartbreak, everyone goes through this." Maybe. But heartbreak over someone who was consistently kind to you doesn't usually come with a compulsive urge to check their location or defend them to your sister. That specific combination is worth taking seriously. Left unaddressed long enough, this exact pattern is where complex PTSD (C-PTSD) tends to take root- not because you're fragile, but because repeated, unpredictable harm is precisely the kind of trauma that produces it. Research on survivors of these relationships puts the number who go on to develop diagnosable PTSD or C-PTSD as high as 50 to 75 percent. This isn't rare. It's the expected cost of what you survived.

The Return Cycle: Why "This Time Feels Different" Every Time

Every time you go back, it feels like a fresh decision. It isn't. It's the same four-step loop running again. Once you can see the loop, "this time is different" stops working on you.

1. Something triggers it. A song, an anniversary, a slow Tuesday night with nothing to distract you. It doesn't have to be dramatic.

2. Your memory does something unfair to you. It reaches for the good moments first-  the ones that felt like proof this was true love- and lets the harm blur at the edges. That's not you being naive. It's a documented bias, and trauma makes it worse, not better: your brain holds on to the idealization phase because it was wired there through the same intermittent reinforcement that built the bond in the first place.

3. Contact happens. A text, a drive-by, a "just checking in." It doesn't matter how small the opening is. Every point of contact re-engages the trauma bond, not just the relationship.

4. Shame arrives right behind it. And that shame, ironically, is what restarts the cycle instead of ending it-  because shame demands relief, and relief is exactly what this person has trained your nervous system to associate with them.

Four steps. Not a moral failing, not proof you're stuck forever. A loop with a shape you can finally see coming.

The Tactics That Make Leaving Harder Than It Sounds

Cruelty alone doesn't build a trauma bond. Timing does. Most articles list narcissistic abuse tactics like a symptom checklist and stop there. I'd rather show you why each one specifically works against your ability to leave.

Gaslighting does the most long-term damage, because it doesn't attack the relationship. It attacks your ability to trust your own reading of the relationship. Once you've been told enough times that you're "too sensitive" or "remembering it wrong," you stop trusting the internal alarm that would otherwise tell you to go.

Love bombing floods the good stretches- the beginning, or every reconciliation- with intensity that resets your memory of who this person "really is." The affection spikes right after the worst moments aren't a coincidence. That timing is the mechanism, not a side effect of it.

Future-faking sells a vivid version of the life you'll build together. It shows up right when you're closest to walking away for good, which is exactly when hope does the most damage.

Intermittent reinforcement is the engine underneath all four-  the unpredictable warmth and withdrawal running in the background of everything above.

Triangulation- whether it's an ex, a friend, or someone new- injects competition into the picture and makes staying feel urgent instead of optional.

Stack gaslighting underneath the other four and the full picture comes into focus. You're not just attached to someone harmful. You've been trained not to trust the part of yourself that would notice.

Signs You're Trauma Bonded, Not Just "Not Over It"

If this is relatable, you may be experiencing a trauma bond.

- You defend them to people who've watched them mistreat you directly.

- Calm stretches in the relationship unsettle you more than conflict does.

- You've left more than once- each time certain, until it wasn't.

- You soften the worst moments when you replay the relationship in your head.

- You feel a physical pull to check on them even when you don't want contact.

- Guilt shows up the second you picture staying away permanently.

If three or more of those landed, it's worth getting a clearer read on what you're actually in before you make another decision from inside the fog. I created the Is It True Love or a Trauma Bond? Quiz to help you get clear. It’s private, quick, and a lot less punishing than another 2 a.m. spiral.

How to Break a Trauma Bond: A Realistic Approach

There is no 3-step miracle on how to “break” a trauma bond. It is actually more of a process of untangling and healing trauma than “breaking” anything. Anyone selling that isn't being straight with you. What actually moves the needle looks like this, in the order it tends to work:

1. Name it- “it’s a trauma bond.”  To yourself, a therapist, one person you trust. Silence is where a trauma bond gets to stay strongest, uncontested.

2. Build real distance. No contact is ideal, but not always realistic, especially if you share a home, a child, or a bank account with this person. Where full separation genuinely isn't possible yet, keep exchanges brief, flat, and factual (i.e. “Gray Rocking”). That alone starves a lot of the intermittent reinforcement keeping the bond alive.

3. Plan for the urge before it hits. Decide now who you'll call or what you'll do the next time you want to reach out. Deciding in the moment, when the urge is strong, is a much harder fight than deciding in advance.

4. Expect a messy process, not a straight line. A brutal day six weeks from now doesn't mean you're back at zero. It means you're a person, not a machine.

5. Grieve the relationship you hoped for, not only the one you actually had. That grief is legitimate even when the relationship itself wasn't good for you.

6. Get support built for this specifically. General relationship coaching and trauma bond recovery aren't the same skill set, and the difference shows up in outcomes. Willpower fights your physiology. The right support works with it.

If you're still tied to this person through co-parenting or family obligation, and full no-contact isn't on the table, the gray rock method- keeping every interaction short, unemotional, and purely logistical- starves the bond of the emotional material it feeds on, even without a clean break.

Conclusion & Action Plan

Here’s the truth and TLDR version: you didn't go back because you're weak. You went back because your nervous system got trained by an unpredictable pattern, the same way anyone’s would. That training can be undone. It takes the right sequence, not raw willpower.

If you're standing at this exact fork in the road right now, here's where I'd recommend you start:

1. Today- take five minutes and name the pattern to one person, even if it's just a text to yourself.

2. This week- if you haven't already, take the trauma bond quiz. It's worth having the results in hand before your first conversation with a therapist, not instead of one.

3. This month- build your urge-plan before the next wave hits, not during it.

4. When you're ready- look into support built specifically for narcissistic abuse recovery. My group, She Rises Collective exists for exactly this stage: women who don't want to heal from this alone.

If any of this sounds like your life right now, contact us. No pressure, no lecture about what you "should" have done differently. Just a conversation about what trauma-informed support could actually look like for you.

FAQs

1. Is it normal to keep going back to someone who hurts me? 

   Extremely common, and it's tied to a documented attachment mechanism, not a character flaw. Common doesn't mean permanent, it means there's a known path out of it.

   
   

2. How long does trauma bond withdrawal last? 

   It varies with the length and intensity of the relationship, but the research above found attachment dropped by about a quarter within six months post-separation. The sharpest physical symptoms of insomnia, obsessive checking- usually ease well before the emotional pull fully resolves.

   
   

3. Can I break a trauma bond without therapy? 

   Some people make real headway through self-awareness, distance, and a strong support network. Because the bond has a physiological component and not just a mental one, working with someone trained in trauma-informed care- EMDR, somatic work, or both-  generally gets you there faster and with fewer relapses.

   
   

4. What if I still love them, even after everything they did? 

   That doesn't cancel out what happened, and it doesn't make you wrong for wanting distance. Love and harm can exist in the same relationship at the same time. That overlap is a huge part of what makes trauma bonds so disorienting to live through.
