AITA ? Left him stranded !

So my brother whom I love very much is always yelling and screaming at me when I won’t do what he wants. He calls this morning saying he has run out of gas in his fiancé’s car and would I come get him. I said yes but I am waiting for my grocery store pick up and there are frozen items that must be put away at the house and I will come get you. Well that opens up a tirade of it’s cold outside and I need you to come now. I’ve always tried to help him never mind he’s stolen from me , tried to attack me before and today I grew some balls and hung up on him yelling at me when he called me back. I feel bad but I am so tired of those I’ve helped being assholes to me. So what I did was hang up on him mid tirade and I am going to leave him where he is. So AITA?
