Can a serial cheater actually change?
I’m trying to understand something about serial cheating and whether real change is actually possible, or whether some people just become better at rebuilding their image after consequences hit.
A guy I was involved with cheated repeatedly throughout his relationship with his fiancée. From what he told me, there were multiple women over the years, someone from tennis, someone from work, me (a neighbor at the time), etc. It wasn’t one isolated mistake. It was a pattern. Everything he told me was a lie, he also was a pathological liar and is a fearful avoidant.
What confuses me is that he wasn’t some cartoon villain who felt nothing. After getting caught, he seemed genuinely shattered. His engagement collapsed. His wedding broke off. His reputation took a hit. He started therapy almost immediately. He spoke about shame, guilt, identity collapse, wanting to become a better man, wanting accountability, wanting to rebuild his life properly.
For a short period, I really believed I was witnessing an actual transformation.
He emotionally opened up in a way I hadn’t seen before. Vulnerable, reflective, self aware. It felt like the consequences finally broke through whatever emotional walls he had. I genuinely thought: “Maybe this is the point where someone changes.”
But then things became confusing again.
He started rebuilding fast. New job, new routine, gym, football, friends, structure, therapy, momentum. Meanwhile with me, it became push-pull, emotional inconsistency, distancing, ghosting, blaming me for parts of his collapse, acting overwhelmed whenever things became emotionally heavy.
And now I sit here wondering:
\- Was the “change” real, or was it just panic and damage control after losing everything?
\- Can serial cheaters genuinely transform long term?
\- Why do some cheaters seem capable of remorse, yet still emotionally discard the people who stood beside them afterward?
\- Why cheat repeatedly in the first place if they supposedly loved their partner?
\- Is cheating like this usually about validation, emotional immaturity, inability to regulate anger, avoidance, entitlement, self-destruction… what actually drives it psychologically?
\- And why does it feel like they sometimes become a “better man” for the next woman, while the person who stayed through the collapse gets pushed away?
Part of me believes people can change if they genuinely confront themselves deeply enough.
But another part of me wonders if some people simply adapt to consequences, build new scaffolding around themselves (therapy, gym, routine, work, self improvement identity), and move forward without truly addressing the deeper emotional patterns underneath.
Especially when the behavior afterward still includes avoidance, emotional inconsistency, distancing, blame shifting, and inability to tolerate difficult emotions.
I’d really appreciate insight from:
\- former serial cheaters who genuinely changed,
\- therapists,
\- people who stayed after infidelity,
\- or people who realized the “change” they saw was temporary survival mode rather than deep transformation.
I’m trying to understand the psychology behind this more than just getting comfort.
He wants to find his lifelong partner, and is emotionally available to date now.
