Hope, the problem is that he knows he can change his mind and have you back anytime he wants. Human beings are strange creature. They want what they can't have and do not want what they can. So you need to start turning the dynamic on its head. When you truly start to move on he MAY decide he doesn't want to lose you and come back around. What I can guarantee is him knowing he can have you back with a snap of his fingers WILL not work. And you can concur that it hasn't worked.
So start moving on, and let him figure out his stuff.
