She won't quit contacting him. What is wrong with her?

So my ex and I have been sleeping together for 5 days now and his baby mom is always calling him. I told her to stop contacting him because he obviously STILL dont want her nor that baby she's pregnant with. She was like, "As long as i'm pregnant with his child, I'm going to contact him. I need his help" like girl he BLOCKED YOU! He barely EVER read her text messages as well. Lol i look through his phone and there are 20+ unread messages from her. What is her problem? Then she calls me stupid for staying with him because i know she's pregnant. That has nothing to do with me. And no, im not mad at him, im mad at her because she won't quit contacting my soon to be man again. I told her if she contacts him again, im going to hurt her.
