Sorry you have to be going though this. Been there and obviously this is painful.
You're right to leave him off your FB. From what I've read here, regardless of what has happened, you seem to be doing the right thing and have the right attitude about how to move on. His indecision is not fair to you and results in abusive behavior. You are far better off without the back and forth.
Nothing that you will read here will indicate that it will all of a sudden be easy now and in the immediate future. It'll be a little better each day that you leave this behind you. You may have HAD something special, but he now seems to be narcissistically involved in his own world. Proof of that (narcissism) is his asking how you are, even though he knows how devastated you are. That's not love on his part.
The sad thing about love is, sometimes it can't conquer all. Sometimes love is not enough.
