One thing that I've learned over the years is that you can't change anyone but yourself. He's not going to stop being the Drama King because you "gave him a taste of his own medicine". To be honest his behavior sounds alot like emotional abuse. You sound like a loving and supportive person, just the type his kind are looking for. Get out while you have a chance. His behavior could develop into more dangerous drama. Men (and women) often start with emotional abuse and once you're beaten down they very often escalate into physical abuse. I know, I've been there. And once he gains dominance over you getting out is really hard. Look inside yourself and see what the universe has given you and get out You deserve so much more than this.
Let me know how you're doing. Remember that it's not much of a relationship if YOU have to work this hard.
Love and light to you
