Yes I agree again. That would make him the good guy. And if he wanted to do that and take that road, power to him, probably the best choice in the long run. But with that said, what she did to him is honestly evil and I personally would not blame OP one bit for wanting to expose her actions to everyone. Even if that makes him a bit of a “bad guy” that day. I say again, that exposing her actions, is not morally worse in my personal opinion than cheating on your fiancé with 9+ men. Idk what I would do in OP’s shoes. Nobody is perfect. He’s going through a lot of pain right now. Maybe her mom and dad and friends should know that she is the sort of person to violate a relationship by behaving they way she did.
