Thank you guys. Having a civilized conversation with him is impossible because once you say something that really hits him where he realizes that he's wrong or he's sees your point of view he starts cutting you off and telling you off and avoiding the subject or not answering your question or repeating over and over while cutting you off "Yeah I know, I'm the asshole" and not letting you put another word in. Honestly I've been ready to cut him out of my life for a while now but I'm stuck in my situation; living with an emotionally neglectful and verbally abusive drunk of a father or a physically and verbally abusive, emotionally traumatized, bipolar drunk of a mother. Your pick. Thanks for the advice, but still getting nowhere.
