What he has done to you in the last week is enough for most people to be glad he's gone. I do not mean that as condescending as it sounds because I stayed for years with someone that most people would have left. I get that part of it.
Have you sought a counselor? You have self-awareness because you are posting here on SR but there is really nothing more we can do or say that will ease your pain. We have re-framed this situation and his actions over and over. Perhaps you need face to face support from a trained counselor to help you over this bump in life's road. He's lproven himself to be an adolescent, cruel, user, alcoholic of a man and he is long gone. This is all about you. Love yourself enough to get real help in getting through it because it can't be much fun living in the space you are in right now. You are unable to even quit talking to him after all that even though you know it is just keeping you in that space.
