One thing was I was on a chat app with him and in groups with random people. I found out he was seeing a woman on there. (This was after he was with me). I took screen shots of what he was telling me (because I knew he was telling her the opposite). I sent it to her and told her what he was about.

Needless to say, I think she thought she was his girlfriend. But in reality, he had ANOTHER girlfriend that he saw regularly. This chat woman lived far away and she only saw him occasionally. (I found all this out secretly going into these chats)
Anyway, this woman completly left the chat and erased herself and told him she didn't want to talk to him again (at least I think that's what happened)
He messaged me right after that. He told me he was sorry he hurt me. Told me I won because the woman in the chat was not in his life anymore and then he said he was also erasing himself from that app permanently! Then he said Bye. That was over a year ago.
I also did some other things but I'm not sure he thinks its me. I catfished him with another profile. I also tried to email screenshots to his wife, but no one ever wrote back so not sure she even saw them. I think he had to shut his facebook down because I think I tried to sign into it. I don't remember now.

I did stupid, silly stuff because I was so hurt.
I feel guilt about it, because I really don't want to hurt him.
