Why is he doing this to me ?? taken all my energy :(?

Honey he doesn't want to be with you. You dumping him hurt his ego and now he is doing his best to hurt you back. Believe me when I say that he will be off as soon as he has had enough or feels he has put you through enough. He is enjoying seeing you suffer with his crap and is a nasty person and needs to be kept at arms length. He thinks so highly of himself - never been dumped before he wants to get over himself! Get rid ASAP girl and cut him off as he is not the sort of person you want in your life at all. He is a first class donkey.
