Glad you are thinking this out fully. I like the suggestions on here that you pose it as both and opportunity as well as a personal need. Letting her have some imput may be the way to earn yourself some points as well. But the bottom line is, even if she is resistant you still need to do whatever it is for you to feel better about the situation. Love the "flip it" idea. Will def give you something to do with your free time and if your M sitch turns around will be a good investment.
I still think that taking this next step will get your W looking at the reality of your situation and get her to a point where she can decide if she wants to work on things or not. Its been a long time and you have been more than patient. But you need to see something in return if you are going to continue on this path.
