My ex is ruining my character..?

My ex cheated on me and we broke up months ago.. I tried to be friends but I just couldn't trust or forgive her. Because of that, bad words were said. I called her an insecure, selfish jerk. We just stop talking. I keep getting subliminal messages from her. How bad I screwed up and how I supposedly hate her which I don't. Just totally making the cheating part my fault. I don't know why since everything was good and we wanted to take the next level.. Until she ran off for a week and cheated. Now she'll telling people it was all my fault. It's been months and she's says she's over it but never shut up about it and tellthe truth. What the hell is wrong with her? Will she ever stop?
