You are in a tough spot. My H was a lot like that till he got his gf - now he wants little to do with me. I also got my hopes up many times, until this new R started.
The fact that there is no one else in his life is, I think, very significant. You have been separated (I think?) for quite some time now, and he would have had plenty of opportunity to start something new, but he hasn't.
My suggestion, FWIW, is a softer take on IMP's. If he says that yes, he does want the D, then starts coming around all nice and flirty, it's time to say, "H, we are getting divorced, we are not friends and this is not appropriate." He will get angry, and you hang up. Say it nicely, but firmly. He needs to understand that you have feelings, you are not just a toy for him to pick or put down when he wants.
This should make him realize that the D won't be everything he wants, but even if it doesn't, I think it will help YOU.
Love, Nicola
