To answer your question, I don't know. I think I have reached the point that limboland isn't oging to cut it anymore. And I think I have reached the point where I realize W may not choose the work on the M (or a better way to put it is I see no sign she has changed her position of NOT wanting to). That doesn't leave much of a choice, in fact, it leaves no choice.
Obviously, if she says she will try MC or try working on the M, then that opens a new option - one I have been clear about from the outset. While I was encouraged by her actions and words the last 6 months, that's gone.
