Help! Anger issues!

Jasmine
I have the most AMAZING boyfriend in the universe. He's my soulmate and I couldn't imagine life without him. But there's one problem: my anger issues are out of control. Before I met him, I was in an abuse I've relationship and once I got out, I had so much built up anger. We've talked about that and he says it's okay to have anger like that but it's not and he doesn't deserve that. We could disagree on something and I totally flip out, call him names, and say hurtful things. I don't want to be like this to him anymore. I need help. Any suggestions?
