Betrayal Trauma and Dating Again Without Losing Yourself
Episode 117
By Sarah Herstich, LCSW | Somatic EMDR Therapist + Host of The Complex Trauma Podcast
Betrayal trauma isn't just about what happened. It's about what your body decided was true because of it. That the floor can disappear. That the person you trusted most can become the source of danger. That your own judgment , the thing you were supposed to be able to rely on , might not be trustworthy either.
If you've lived through complex trauma or emotional neglect, betrayal doesn't land as just a painful breakup. It lands on top of everything else you already know about how love can go wrong. And that changes things.
In this episode of The Complex Trauma Podcast, I sat down with Joe Sanok , former Gottman-certified marriage therapist, host of Practice of the Practice, and author of Dating After Betrayal , to talk about what betrayal trauma actually does to the nervous system, how a complex trauma history makes it hit differently, and what it really looks like to move toward new relationships without dragging the past ones into them.
Joe didn't come to this work from the outside. He was a married therapist who studied relationships for a living, believed in doing the work, and still found himself waking up every morning in an RV next to someone who was already leaving. His wife left with her surf instructor. He became an unexpected single dad. And then he had to figure out how to get through it , not as a clinician, but as a person.
What Betrayal Trauma Actually Is
Betrayal trauma occurs when someone you depended on, someone whose proximity felt like safety, violates that trust in a significant way. The research on this goes back to Dr. Jennifer Freyd, who defined it as what happens when "the people or institutions on which a person depends for survival significantly violate that person's trust or well-being."
That word survival matters. This isn't just about disappointment or hurt feelings. When attachment and threat collide, when the person who was supposed to be safe becomes the source of danger, the nervous system responds the same way it does to any other survival threat.
Hypervigilance. Intrusive thoughts. Difficulty sleeping. Emotional dysregulation that swings between flooding and shutdown.
Symptoms that look a lot like PTSD, because neurologically, that's exactly what's happening.
The brain learns to anticipate betrayal. It starts scanning for signs of it even when none are there. And then you meet someone new, someone who is genuinely kind and present and doing everything right, and your nervous system still doesn't believe it. Not because you're broken. Because your body is doing exactly what it learned to do.
Why a Complex Trauma History Makes Betrayal Hit Differently
If you grew up in an environment that was unpredictable, or where love came with conditions, or where the people who were supposed to protect you were also the ones who caused harm, your attachment system already has a complicated relationship with trust.
When current betrayal lands on top of that history, it doesn't just add to the pain. It confirms a story your nervous system has been carrying for a long time. That people leave. That safety isn't real. That you should have known better. That you can't trust yourself.
As Joe put it, the core of betrayal is someone who was supposed to love you doing something to you. That maps directly onto early attachment wounds. And when those two things layer on top of each other, the response can feel completely out of proportion to someone who doesn't understand the history underneath it — and completely coherent to the person living it.
This is why betrayal trauma work can't just address what happened in the relationship. It has to address what the relationship activated.
The Nervous System in the Aftermath of Betrayal
What Joe described from those early mornings in the RV is something a lot of people with betrayal trauma will recognize. Waking up and having a millisecond where everything feels normal, and then the body remembering. The looping. The thoughts that won't stop. The sense of not knowing up from down.
That's not weakness. That's a nervous system that has lost its primary source of co-regulation and doesn't know yet how to orient to safety without it.
What Joe found his way to, almost intuitively before he could name it clinically, was a morning routine that helped his system move through the activation rather than just sitting in it. Meditation to get present. Journaling to externalize what was spinning. Then movement, hard physical movement, specifically to give the anger somewhere to go. Walking miles to music that matched the rage, because the mobilizing energy needed a channel. Planks that started at one minute and eventually reached five, because his body needed to feel strong in the middle of something that felt completely out of his control.
From a somatic standpoint, this is exactly right. Betrayal trauma mobilizes the fight response. That energy has to complete somewhere or it stays stored in the body. The question isn't how to make the anger go away. It's how to give it a place to move through.
Building a Support Committee Instead of Going It Alone
One of the most useful frameworks Joe shares in his book is what he calls the committee, a deliberately assembled support network where different people hold different roles, rather than putting all of that weight on one person or trying to carry it alone.
For Joe, this looked like a friend who had navigated divorce and co-parenting well and could hold hope for him. A friend who remembered every wrong thing and gave him permission to be furious when he was trying too hard to be evolved about it all. A spiritually grounded friend who could hold the bigger questions. And a distraction friend — someone who would go out, stay out too late, and make space for something other than grief.
This matters for a few reasons. People with complex trauma or attachment wounds often have a pattern of putting the full weight of their emotional world on one relationship. When that relationship ends in betrayal, the loss is total, not just the person, but the entire support system. Building a committee is a way of distributing that back out so that no single relationship has to hold everything.
It also makes it harder to recreate the same dynamic in a new relationship, because the need for one person to be everything has somewhere else to go.
How Betrayal Trauma Shows Up in New Relationships
The hardest part of dating after betrayal isn't the early stages. It's when something in the new relationship, a tone of voice, a moment of distance, a feeling you can't quite name, activates the old pattern and suddenly you're not responding to the person in front of you. You're responding to the story your body learned.
Joe's therapist gave him a simple technique that cuts through this: when something feels like your last relationship, ask what's similar and what's different. Not to talk yourself out of your reaction, but to get specific. Yes, this person is someone who loves you. Yes, that person is also someone who loves you. What is actually different here?
This is the felt sense work that shows up in trauma treatment all the time. The nervous system generalizes. It takes patterns from the past and applies them to the present because efficiency in threat detection is a survival advantage. The work is not to argue with the pattern. It's to gently, repeatedly, offer the body new information. This person has a job. This person is doing their own work. This person is not that person.
It takes time. Even when both people in a new relationship understand trauma, even when both can name what's happening, it's still hard. The activation is real. The history is real. That doesn't mean the relationship is doomed. It means it requires more intentional navigation.
On Knowing When You're Ready to Date Again
There's no clean answer to this. Joe is honest about that.
What he does say is that readiness has less to do with timing and more to do with capacity for honesty, with yourself and with other people. He entered the dating world being transparent about where he was. He wasn't looking to settle down. He was in a 17-year marriage and needed to understand who he was outside of it. He said that clearly, even when it made things awkward, even when he ran into people he'd been dating in the same place on the same night.
For people with complex trauma histories, the pull to jump into the next serious thing can be strong. The window of aloneness feels unbearable, especially if you've never been comfortable being alone with yourself. What Joe's therapist named for him was that he had missed a developmental window of figuring himself out, going from faith-based commitment directly into marriage without the period of exploring who he was and what he actually wanted.
Trying to bypass that window again, moving quickly into the next committed relationship to avoid the discomfort of the in-between — often just recreates the same dynamic in a new container.
The in-between is part of the work.
The Absence of Presence and the Presence of Absence
One of the most honest things Joe shares in this conversation came from his friend, musician Seth Bernard: when you go through betrayal and divorce, you'll encounter both the absence of presence and the presence of absence.
The absence of presence is when the person is just gone. The presence of absence is when the emptiness itself becomes something you have to sit with, the quiet in the house, the space where routines used to be, the moments when you realize you've been structuring your whole life around someone who isn't there anymore.
Joe's solution to this wasn't to fill the space with another relationship. It was to fill it with things that were actually his. Watercolor painting. Improv. Walks with friends. Things that required his presence and gave him something to come back to himself through.
This is the rebuilding of self that betrayal trauma disrupts. When a relationship ends in betrayal, especially one you were deeply merged with, you often don't just lose the person. You lose the version of yourself that only existed in relation to them. The in-between is where you find out who you actually are without that.
What Betrayal Trauma Asks of You on the Other Side
Joe says something near the end of this conversation that I keep coming back to. He says he wouldn't change any of it. Not because it wasn't terrible. It was. But because he got through the thing he feared most, being the divorced guy, the one who failed at marriage, the person his faith tradition told him he wasn't supposed to be, and he came out more himself than he was going in.
That's not a promise that betrayal will lead to growth for everyone. It doesn't always. It requires the right support, the right tools, and the willingness to stay in the discomfort long enough for something to shift. But it does suggest that the story betrayal tries to tell you about what your life is now, that it's over, that you're unlovable, that your judgment is broken , doesn't have to be the last word.
Your nervous system learned something from what happened. That learning made sense at the time. The question is whether you can, slowly and with support, offer it new information.
FAQ: Betrayal Trauma and Dating Again
What is betrayal trauma?
Betrayal trauma is the psychological and nervous system response that occurs when someone you depended on for safety and connection significantly violates your trust. It's distinct from ordinary hurt because the betrayal comes from an attachment figure, someone whose closeness felt like protection. When that person becomes the source of threat, the brain and body respond as they would to any survival threat, producing symptoms that can look like PTSD: hypervigilance, intrusive thoughts, emotional dysregulation, difficulty trusting, and a nervous system that stays on alert even when the danger has passed.
How does a complex trauma history affect betrayal trauma?
If you grew up in an environment where love was inconsistent, conditional, or came alongside harm, your attachment system already has a complicated relationship with trust. When current betrayal lands on top of that history, it doesn't just add to the wound. It activates the earlier one. The nervous system recognizes a familiar pattern and responds with the full weight of everything it's already survived. This is why betrayal can feel impossible to get through for some people and manageable for others, the history underneath it matters enormously.
Why is it hard to trust someone new after betrayal even when they're good to you?
Because your nervous system learned something from the betrayal. It learned that people who feel safe can become unsafe. That love can turn. That your own instincts might not be reliable. So when someone new comes along and does everything right, the alarm system is still running the old pattern. It's not about them. It's about what your body decided was true after the betrayal, and it takes time and new experience, not just logic, to update that.
How do you know when you're ready to date again after betrayal trauma?
There's no clear timeline, and anyone who gives you one is probably oversimplifying. What matters more than timing is whether you can be honest, with yourself about where you are, and with other people about what you're looking for. Rushing into a new serious relationship to escape the discomfort of being alone often recreates familiar dynamics in a new container. The in-between period, as uncomfortable as it is, is part of the work.
What actually helps when you're in the acute phase of betrayal trauma?
Movement that matches the intensity of what you're feeling. Anger especially needs somewhere to go, hard walks, physical exertion, anything that gives the mobilized energy a channel. A support network that doesn't put all the weight on one person. A therapist who understands trauma, not just relationship dynamics. Honest journaling. And time with the discomfort rather than compulsive attempts to escape it, whether through the next relationship, substances, or staying so busy you never have to feel it.
How do you stop projecting your past relationship onto a new partner?
The most useful framework is asking what's similar and what's different, not to talk yourself out of your nervous system response, but to get specific. When something activates the old pattern, slow down and get concrete. What does this person actually do? How do they actually behave over time? The nervous system generalizes for efficiency, applying old patterns to new situations because that's how threat detection works. The work is to repeatedly, gently offer the body new information through real experience, not just reassurance.
