Working my angries out

I suffered from verbal abuse in my last relationship, and I also learned to be a verbal abuser. I called my current boyfriend names the other night. I was angry, and instead of dealing with it, I used rage to try to hurt him. 
I realized these past few weeks, that I've got a lot of work to do on myself. I am on the verge of becoming co-dependent. I was scared, but realizing it and knowing there's something I can do about it helped me feel better.
