My ex whose also the father of our children would always abuse me, cheat on me and control me. I finally left with our kids and I haven't put him on child support. I don't bother him for anything nor do I interfere with his relationship (the same girl he was cheating on me with while I was pregnant) yet he still speaks badly about me. I have a feeling he's mad I'm not chasing after him and don't need him for anything. He always finds a way to bring me up.
