I know my ex went around bashing me and making me out to be some emotionally abusive a-hole to anyone who would listen when she left. She did it to portray herself as the victim and get people to approve of her decision, and cheer her on.

I did just the opposite with our friends, when I was asked about her. I would just say it didn't work out and that I hope she finds what she's looking for.

What's crazy is it's been two years since we split and had any contact with each other, and my mom has told me my ex has called her and expressed regret about leaving me. Go figure...

There's nothing you can do about it so let it go. I think most rational people will be able to see what she's doing considering she is the repeat offender cheater between the two of you.
