You need to read your first line of your first post in here. You know its a toxic relationship. It's unhealthy for both of you. You said you live as roommates but Im reading that you both treat each other like you are begrudgingly together. So much hostility, aggression, drama. It's not worth it. You've indicated all of the ways he is not right for you. What on earth makes you think he will change? You know what to do. Say goodbye, good riddance, and move on.
