Time for counseling... or maybe a restraining order?

I don't think there's any point in asking him because if he realised that, he would apologise and not tell you not to contact him. You also say that he has a tendency to throw fits and scream and verbally abuse you. So if he hasn't realised it all those times before, do you honestly believe that he will realise it now when you ask him?
He obviously has issues and is abusive. If I were you, I'd not contact him again. I know it can be hard to lose someone (even a shitty someone) whom we are used to being around. But after that initial phase of feeling a bit sad comes the phase of being extremely happy that you got rid of that person. Nobody should be with a partner who freaks out for no reason whatsoever and becomes abusive (be it verbally or physically). You need to just let it/him go. He isn't going to change.
