My guess is she's trying to keep all options open. Doesn't want to give up OM. Has doubts about OM. Partly misses 'home.' Doesn't want to go back to how she felt 'before.' Wants to check if you're still 'on the hook.' It's all a little crazy and may not change any time soon.
The main thing is to stay detached from 'crazy' and not spend too much time worrying about what it all means. Your W probably doesn't know that - confusion and more confusion.
I think you are on a good course though and I think you maintain good self-control in the face of these challenges. Minimally available, though pleasant, rebuilding your life etc. That's all good stuff. Best to leave her to work through whatever may be going on and avoid a triangular relational situation above all. Xx
