I'm still expecting this to end in D, but I will not stop trying and I am glad I have found a better way of communicating that leads to connection.
Unfortunately, we can't know how things will eventually turn out because you have no idea what your W will choose to do. BUT, you can fight for your M (even when she's not willing to) and you are on the right path to do that. Stay focused and follow the process. I know it hurts when people say things like "You'll be a better person after all of this, even if you don't stay married" or "You'll be ok even if you get D" because the truth is you don't want a D and you don't want a life that doesn't include your W. But you don't have any control whatsoever over your W so all you can do is focus on you and what you need to do. The good thing is that by doing that, you have a real fighting chance at saving your M.
