Hold up. You don't want to give up on HIM because...? Just from reading your post, I see that he's an alcoholic and an abuser who has been in jail a few times and who has beat you up more than once. We're not talking about a gem here...
It doesn't matter that he MADE you promise anything. You do not have to keep a promise made to him when you were scared for your life!
I'm sorry your mom isn't being more supportive. But you know who is? The people here. They saved my butt more than once. And of course the nice people at Al-Anon, along with my therapist.
If you KNOW you have a weakness for him, then take steps to make sure you don't give in. Surround yourself with support, keep yourself busy and safe, delete his number, email, whatever, and refuse to see him. Eventually, it'll get easier.
