I'm not going to listen to my (ex) gf
Did she have something important to say?
I've heard it all before and I'm done with having a relationship.
I think you're fine doing that.  Nothing says you need to stay in touch with an ex.  Move on and find someone better!
Aye, I'm going to seek the next ex to say a lot of horrible things to.
Most people move on after a relationship ends. I doubt your next relationship would want you to talk about your ex all the time though. So maybe burry it and move on before you do that.
