Your sitch may be different because H is saying he's cooperative. But words aren't actions.

My experience with MC involved similar vocabulary. First, she agreed to do it, "to figure out why this happened to us" and to help her "decide" whether she wanted to recommit. She had decided to leave the MR long, long ago.

I also got the "relief" story. The relief was that finally she would get what she had wanted for a while, plus getting it in the context of "letting me down gently" via MC and the whole "we tried our best" baloney.

MC was just more pressure/pursuit. In the end she felt less cruddy about herself and I felt worse than ever. The end of MC was basically BD #2.

Just being the devil's advocate here.
