Ssarah, you never know what the heck they are going to do or the situation with ow. It was a few month after h telling me he wants a d and not pursuing... I felt the same way as you- like what the heck? Maybe he does not want to. (Which I really don't think they know what the heck they want other than to feel good by the minute.)
I was told via text message that he was pursuing divorce. Nineteen years and I get dumped through text-- just be prepared. Not that its going to happen, but I wouldn't read into it too much as a sign. They act on spur of the moment, not really on realistic future plans. Hang in there! I can tell you are very strong.
