You can move forward without immediately filing for a divorce. You can stop focusing on everything WW is doing and focus on your own well-being. GAL. Be the person only a fool would leave.
I think the concern is that you've been changing your mind about what you want based on what your WW does. If you want a divorce, fine. But just the other day, you were convinced that WW is out of the fog and that it should be easy to get the R back.
