I think that Antonia has given you good advice. He sounds like he is still within his FOG. You need to keep moving along with your life "as if" he is not coming back. The encounters you had with him are probably a function of him having some clarity. A touch and go. There probably is some relief on his part that the divorce is moving along and he is getting rid of you. I wish I could see something more positive but when he is really out of the FOG you will have no doubt. Now thats all you have is doubt.
It sounds to me as if you were pursuing him and he let you catch him. That is not going to be the basis of a new marriage IMHO.
