My XWF's AP was never a real person to me. I knew him and knew that he had a thing for her but never acted on it, even when she was single. I know for a fact that she initiated and he just enjoyed the ride.
I also know he was terrified of me and avoided me fastidiously. I had about five inches and 40 pounds on him, plus was a trained, competitive fighter, so I could have just looked at him and he would have left a POSOM-shaped hole in the nearest wall.
So, sure, I forgave him.
As for her, I immediately cheated back with a woman who was better looking, smarter and had more personality than her. Plus, my XWF was pretty trashy (as I write this I'm amazed that we were such an item...but I digress) and my AP came from a fantastic family. I went to her in part because I knew my XWF felt threatened by her. Plus, she hated my XWF and was cool with it. She may have hoped I'd break up with the XWF, but I didn't (big mistake).
So, in short, I did it to punish her. I thought we were even at that point, so I didn't really feel the need to address it like an adult.
And it did not go well for me.
She waited until I was in a locked down military school for months and then proceeded to sleep with every acquaintance I had who would have her while rubbing my face in it. And she timed this (coincidentally) right after my sister had died at 28 years old. She almost seemed to relish how much pain I was in. It was brutal.
So, while I may have forgiven her for her betrayal (at least that's what my dumb ass believed), she clearly did not forgive me.
I did get some mode of justice ultimately because I ended up marrying someone who's my best friend, and am still married to her 30 years later. I'd heard that it drove her crazy that I wasn't outwardly destroyed like she thought I'd be.
I haven't heard about or from the XWF in over 15 years, but at that time she was on her third marriage and was still working entry level jobs.
EDITED TO ADD: I went back and re-read this post and see that it could be triggery as hell. I was trying to make the point that this was how I felt about my AP and my tactics at the time...and my response backfired spectacularly. I do feel like my life now with my wife is the best revenge I could ask for, but I apologize if the rest was upsetting to anyone.
