My ex wife says she's happy without me, I'm not buying it.

I'm a 42M, my ex is a 42F. We met at the beginning of 2023, lived together for about 10 months, got engaged in late summer of 2023, got married in December 2023, separated in February 2024. We had a bit of a rough relationship, lots of little things that made me uncomfortable, but I loved her and she was my first real gf, so I was willing to work through it and forgive her for the little things.<br><br>Then, at Christmas, she said she was being unfaithful because she had no libido and didn't feel attracted to anyone. I was pretty upset and hurt by this, but I believed her, because she seemed genuinely remorseful and I knew she was stressed with work. However, after Christmas, things got worse. She started blowing me off, stopped responding to my messages, and eventually told me she wanted a break. I didn't push it, thinking she was stressed from work.<br><br>But in late February, I found out she had been having an affair the entire time we were together. She had been seeing someone she had met online since October 2023, and had even gone on a date with him a few times. I was devastated, and she eventually admitted to it when I confronted her. She seemed genuinely remorseful and apologetic, but I was angry and hurt.<br><br>We separated, and I moved out. She then started acting like everything was fine, like I was the one who was in the wrong for being angry at her infidelity. She told me she didn't think it was that big of a deal and that she was happy without me. I don't believe it. I think she's just trying to make herself feel better. But what if I'm wrong? What if she really is happy without me? Is it possible for someone to be happy without you after they cheat on you?<br><br>TL;DR: My ex wife says she's happy without me, but I don't believe it. Is it possible for someone to be happy without you after they cheat on you?
