I hope you won't put 100% of your hope into the possible MC. She may go to the first session and refuse to return. Guess I may sound like a downer, but I want you to be emotionally prepared in case the MC doesn't work out.
From what I have read, I don't believe it is uncommon to have some back sets before finally able to piece the M back together. And I have noticed something about many LBH's. Many of them have all their focus on getting the WW back. But somewhere along the way, they have not dealt with certain issues of their own. B/c once the WW does come back, then it is as though the LBH has second thoughts about it. He begins to experience anger or problems with total forgiveness. These are areas that have to be healed or he will not fully be able to move forward with life, and the M can't be what it needs to be.
JMHO, but I have to wonder if part of the problem is b/c the H wants to get past all the pain and get on with normality again. He thinks if the A ends and he gets his W back that his problems are over. However, he has spent all his mental energy on his W and neglected himself. That is only one reason we tell newcomers to get their attention off the WAW and on themselves.
Unfortunately, this healing issue is something that takes time, as surely as if you had had your heart cut out and trying to live with a new one.
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!
