Trust issues

Ladies this is a long one. I was in a 6 year relationship we broke up around Christmas. My ex partner was very mentally abusive and controlling. I'm with someone new now but I can't trust him. I know this is all in my head but I convince myself he's going to leave or he's cheating. I'm pushing him away and I just can't help it. This morning I was even considering breaking up with him because I don't want to put him through my moods anymore and also I don't feel good enough for him :(
