We are dealing with very similar circumstances. You have made it clear that you want your M to work. You have asked for honesty and transparency but your W is not giving it to you. You have shown your W your changes and that the road to R is smoothly paved if she makes that choice. You are doing a solid job of following the rules. "Your smallest consistent action will be noticed far more than any words you could say or write." In my opinion I would let it play out rather than tell her to move.
