I'm glad you laid all the cards out on the table and explained to W that if she feels she is done then get the paperwork started. Between that and you taking off your ring you showed her that you are willing to move on without her. That got her attention. Whether or not she chooses to act is yet to be seen. But I think it's great for you either way. You're moving forward with or without her and working on your own happiness.
I say good work and keep moving down that path. I know it feels like you've been here before. What do you think triggered the relapse last time?
