AITAH after telling my brother I don't want anything to do with him?

Ok so. For context my brother is an alcoholic. I got a ride wlfrom him to work cause he was going that way anyways cause he was drinking with his buddies. I was to get a ride from someone else in the morning.I get off and am on the way home. He calls me "Hey you ready?" "What for? I already have a ride home". "You were supposed to g7ve me gas money blah blah blah". I didn't realize that was the case. If I knew I would've told him not to bother as I didn't have money for gas at all at the time. I tells him he needs to stop relying on me and that if he would stop spending $80 a week to get drunk hed have his own gas. He blows up and threatens to break my legs. And otherwise beat the shit out of me. So I stopped talking to him. I ignore him. I flat tell him to stay away from me. I don't want people like that in my life. Its been a week He keep apologizing. Its really bugging him. But like. I don't care. That's not a mood I want in my life. I've finally hit a point of indifference with him where I just don't want anything to do with him. AITAH?
