I had several 1:1 conversations with the MC's I went to. They said that people come to MC for a variety of reasons:
1) Trying to give the appearance that they "tried" when in fact they had already given up. This is public face-saving 2) Trying to help the other person come to terms with the fact that they have decided to leave 3) Trying to get a third party to validate that they are right and the other person is wrong 4) Trying to save their marriage by being willing to work on it.
They said that 95% of the time, one person is coming for reasons 1-3, and the other person is coming for reason 4. When only one person is in, MC has a 0% success rate.
They said that people usually come in about three years too late, when one party is already fully checked out.
It sounds like you're fully in this scenario where you're in group 4 and W is in some combination of groups 1-3. In that scenario, you have almost no chance of success with MC.
I would strongly recommend individual IC and telephone DB coaching as being a *much* more effective course of action for you.
