Okay, I've been thinking this for a while now. Problem is, it's just my gut, based on what you write and boils down to nothing more than mind reading. Thing is, I really do think your W is trying. I really do. Why else would she do as much with you as she has lately? What W that does not want to be with H spends the hours with you that she does? And now another baby step forward it would appear.
I don't want to try to suggest what to do here. I really don't know. That's better left to an expert like sand. All I know is from where I sit your W is more in that out. She clearly needs to be prompted forward. I would just not push too hard or give an ultimatum. I think AS is correct in this is all about baby steps. One step forawd and two back only with you it appears to be two steps forward and one back.
I'd certainly keep doing what you are doing. It certainly seems to be working.
