I have no real advice from my own experience as I haven't had WW invite me to anything and she is now moved out. I am in the same place as you though, wondering if I want R when the dust settles.
I recommend you tread lightly in this situation tho. Personally I would still act as if and continue to DB. However that also involves validating and showing you care. It can be very hard not to jump at any scrap she throws to you.
I guess the best I can do to advise is keep with the program. Don't be cold to her. Hopefully someone with more experience can help you through this
Keep up the positive changes my friend. It makes me happy to see the personal progress you have made
The person that you will spend the most time with in your life is yourself, so make yourself as interesting as possible.
