I want to preface this post by saying that I am not an expert. Everything I’m sharing is based on my lived experience, along with the work, counselling, and research I’ve done since my husband’s betrayal.
This is an incredibly vulnerable post for me. I’m a real person. This is my real life, and talking about physical intimacy online can feel really confronting. But when I started this blog, I promised myself I would share the parts of this journey that might help someone else feel less alone. Intimacy after betrayal is one of the topics I’m asked about the most, so… here we go.
I think people often assume that if someone physically cheats, it must mean there wasn’t any intimacy in the relationship. For us, that wasn’t true. Yes, things had naturally changed during pregnancy and postpartum, but our physical relationship wasn’t non-existent.
After my husband’s infidelity, intimacy looked very different—and honestly, it wasn’t what I expected.
In the beginning, I experienced something called hysterical bonding (also known as hyper-bonding). That was followed by a period of withdrawal, then a phase where my emotions constantly fluctuated and intrusive thoughts became overwhelming.
It’s important to remember that infidelity can be an incredibly traumatic experience for the betrayed partner, and everyone responds to trauma differently. Not everyone experiences hysterical bonding after betrayal, and if you don’t, that’s completely normal too. There is no right or wrong way to heal.
What is hysterical bonding?
Hysterical bonding is a trauma response where someone experiences an intense, almost obsessive desire for physical and emotional closeness immediately after a significant relationship betrayal.
I’d never even heard the term until I stumbled across a podcast discussing infidelity and intimacy. As I listened, I realised they were describing exactly what I had been experiencing.
For me, it started almost immediately—within about 12 hours of discovering the affair.
It was confusing.
It was overwhelming.
And, if I’m being honest, I felt ashamed.
When I first confronted my husband, my thoughts certainly weren’t, “I want to have sex with this man.” They were much closer to, “I want to rip your balls off and feed them to a shark.”
But after hours of crying, talking, asking questions, and trying to process what had happened, something shifted.
During that first month, we were physically intimate multiple times a day. After that, it gradually slowed to once a day or every couple of days, but the need for closeness on my part was unlike anything I’d ever experienced before.
Why does it happen?
Hysterical bonding can happen for many reasons.
For some people, it’s driven by the fear of losing their partner. The shock of the affair can trigger separation anxiety, creating an overwhelming urge to reconnect physically in an attempt to “fix” the relationship as quickly as possible.
For others, especially those with childhood trauma or experiences of abandonment, physical closeness provides a sense of safety and security during an incredibly distressing time.
There’s also the confusing reality that your partner is usually the person you instinctively turn to for comfort during life’s hardest moments. When they’re also the person who caused the pain, those instincts don’t simply disappear overnight.
On a biological level, physical intimacy releases dopamine and other feel-good chemicals that can temporarily reduce anxiety, making it understandable why some betrayed partners crave that closeness.
Some people also begin blaming themselves for the affair. They convince themselves they weren’t enough, weren’t attractive enough, or weren’t attentive enough. That can create a desperate desire to “prove” they can be more—or somehow be better than the affair partner.
If I’m honest, I related to almost every one of those reasons.
Part of me wanted to rebuild our connection.
Part of me wanted reassurance that I was still wanted.
And another part—one I’m almost embarrassed to admit—wanted to prove that it doesn’t get better than this.
My self-esteem had been shattered. Somewhere deep down, I felt like I had to overcompensate.
My competitive side kicked in, and I found myself thinking, I’ll show him.
It’s strange to admit now, but that’s where my head was.
For the past year, I’ve often felt like I’ve been faking confidence until I believed it myself.
And somehow… it’s actually been working.
So, how do you rebuild intimacy after betrayal?
The short answer?
I don’t know if I completely have the answer.
The longer answer is this: give it time.
Be patient with yourself.
Your partner needs to be patient with you, too.
Keep communicating, even when it’s uncomfortable.
Your wants and needs will probably change from one week to the next, sometimes even from one day to the next. That’s normal.
Intrusive thoughts are brutal. They might happen constantly, or they might only appear every now and then. Whenever they come up, and if they leave you feeling distressed or disconnected, talk about them.
Your partner might feel frustrated hearing about the affair again. They may think you’re “bringing it up” unnecessarily. But if talking through those thoughts helps you process them and gives you reassurance, then they need to be willing to have those conversations.
Healing isn’t linear.
Neither is rebuilding intimacy.
And this probably goes without saying, but I’m going to say it anyway:
Never feel pressured into physical intimacy before you’re ready.
If you’re not ready, that’s okay.
You should never be made to feel guilty for struggling with something that someone else chose to do to you.
One final thought
Some of the biggest improvements in our intimate relationship actually happened outside the bedroom.
Go to the couples counselling.
Have the difficult conversations.
Go on dates.
Laugh together again.
Spend quality time together without any expectation of physical intimacy.
Don’t be afraid to ask for reassurance when you need it. If you have questions that still need answers, ask them.
The stronger your emotional connection becomes, the stronger your physical connection has the opportunity to become as well.
Healing intimacy after betrayal isn’t about pretending the hurt never happened.
It’s about slowly creating a relationship where safety, honesty, and connection can exist again.
And if you’re reading this while wondering whether what you’re feeling is “normal,” I hope this reminds you that you’re not alone.
Let’s rise together,
