My boyfriend of 13 years cheated with a co worker and although I left him we got back together and tried to work things out, however he still worked with her up until a few months ago and did not tell me she had left. I told him before when she quit or he quit I was telling her now husband what they did. No one knows on her side at all of the affair. I feel like she thinks she won in this situation, and I confronted him on why he didn't tell me she quit, he said that things were going great and didn't want to bring any of that up. He knows my anxiety regarding him working with her and that was a big hurdle, we weren't at a good place for him to up and quit either. So now I'm at the final point of closure in my opinion, I want to tell her husband it's not fair at all she got out of this clean, I know it's probably better to just leave it alone but there is a part of me that wants to ruin her life.
