Can a Relationship Survive Infidelity? What I've Learned After 18 Years of Couples Therapy
By Pia Arrendell, LMFT | Couples Therapy & Betrayal Recovery, Asheville, NC
This is the question I hear most. Usually, it comes in just a few words, typed at 2 a.m., or whispered in the first session before someone's partner has even sat down.
"Can we come back from this?"
After nearly two decades specializing in couples therapy — and specifically in the aftermath of infidelity and betrayal — here's what I know: the answer is almost never simple. But it is almost always more hopeful than people expect.
The Question Underneath the Question
When a couple sits down in front of me after an affair has come to light, the real question isn't usually "can we survive this." It's: "Is this relationship still worth it? And can I ever trust again?"
Those are two different questions, and both of them deserve real answers.
What research tells us, and what I've seen in my practice, is that roughly 50-70% of couples who experience infidelity stay together. But staying together is not the same thing as healing. Some couples remain technically intact while staying emotionally stuck for years. Others do the real work — and end up with a relationship that's deeper, more honest, and more connected than what they had before.
The difference almost always comes down to what happens after the affair is discovered.
What the Research Actually Shows
The couples who are most likely to rebuild trust after infidelity share a few common factors:
The unfaithful partner takes genuine accountability, not just "I'm sorry," but a real reckoning with what happened and why.
The betrayed partner is given time and space to grieve, rage, question, and process without being rushed toward forgiveness.
Both people are willing to look honestly at what was happening in the relationship before the affair, not to excuse what happened, but to understand it.
They get professional support that is specifically trained in betrayal and infidelity. This is not territory for general couples counseling.
What doesn't predict survival: how long the affair lasted, whether it was emotional or physical, or how much the betrayed partner cries in session. What matters is the quality of the repair, not the size of the wound.
The Mistake Most Couples Make
The biggest mistake I see after infidelity is trying to skip the hard part.
The unfaithful partner wants to move forward. They're ashamed, they hate watching their partner in pain, and they want to believe that if they just say the right things, it will all go back to normal. So they push for forgiveness before the process of repair has actually begun.
The betrayed partner wants the pain to stop. So sometimes they go along with it, trying to "get over it," suppressing the questions, agreeing to move forward even when they don't feel ready.
What this creates is a surface-level reconciliation sitting on top of an unprocessed wound. And it almost always resurfaces — usually months later, and usually louder.
Trust is not rebuilt through promises. It's rebuilt through consistency, and through small moments repeated over time until the nervous system of the betrayed partner finally starts to believe it's safe again.
That process takes longer than most couples expect. And it requires both people to be more honest, more patient, and more courageous than they've probably ever had to be.
When Couples Therapy Isn't Enough
Weekly one-hour sessions can be a good starting point. But for couples in serious crisis after infidelity, I often recommend a couples intensive — an extended, immersive experience that gives you far more time to do the work than weekly therapy allows.
At my practice in Asheville, I offer couples intensives for exactly this reason. When the wound is deep enough, you need more than an hour a week to get to the bottom of it — and more than an hour a week to start building something new.
