Most LBS's talk their way out of the relationship by having R talks where they try to talk their WAS back into the R. Learn some validating phrases, learn how to withhold your "advice" for now.
If she states that she doesn't think you can change long term, just validate,or maybe ask a question if you don't understand. I can certainly understand why she is doubtful, it's hard for people to make changes.
Definitely don't discuss her changes yet. It might be many months or longer before she is ready.
