He did me wrong and now he is the weird one??? help?

I am upset but in reality it woke me up. I still remain cool and cordial after I told him what a jerk he is. He didn't want to break up but he gave me no choice. Now I am functioning normally and he is the one who is depressed. He lied and told his family he needed to be alone right now when the truth is I dumped him. Why is he the one lying and acting depressed when he is the one that pushed the envelope so far until it was over?
