Most Helpful Guy
Most relationships go on much longer than they should before something happens and it comes to an end. He could have seen it ending was inevitable and excepted it a while back. Also if he was feeling hurt and disrespected by you over a long period of time he probably has a lot of resentment towards you

Well if you get dumped, it is normal to not want to exactly, fight over the other person who just dumped you. It's not on the person who dumped to woo anyone over or try to convince the other. I think he is hurt by you but he's not going to go pouring his heart out to someone who just dumped him.
