Well, my thoughts are that the person who wants the D, needs to see how divorced life looks. No more family get-to-togethers. It might be painful, and it might bring to light some things your W is trying to keep in the dark, and it might cause a fight..…….but what do you have to lose that you haven't already lost? Stop serving her cake! She needs to see some reality of her decision to break up her M.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
