He sounds like a real narcissistic psychopath with no empathy what's so ever. I would throw things at his head too if he did that too me, I would be a viper if he did to me what he did to you. He sounds selfish and that's what addicts are... Sorry but he doesn't care about you only when he is lonely or bored ... You deserve better I know it hurts i have been where you have been but dating him sounds like a death sentence
