I don't believe this M can be saved but DBing has helped me deal with this and look at myself.
But you don't really want THIS marriage to be saved, do you? You'd like your W to try a new marriage with you, but what's the point in saving the old one? So if this next step moves you closer to getting a new R with your W... well, maybe that's worth something.
