One thing--you do NOT want to ask for "anger management." Batterers' intervention is different. Abusers are generally able to manage their anger pretty well (although your guy was flipping out even when the cops got there, presumably he wasn't attacking them). They feel entitled to behave the way they do when you aren't pleasing them.
I'm glad you've made contact with Victim Services--I recommend you take advantage of any resources you think might be helpful. I really appreciate the work that dedicated advocates do, and I'm also pleased to hear that it sounds like the police handled things well.
