I am not sure you want my opinion but here goes.

I went to 6 months of MC. We finally quit when my W refused to work on our marriage and we really were not accomplishing anything.

My wife used the counseling to justify her desires to get a divorce.

I think in retrospect no MC can do much with someone who is in MLC. Maybe MWD as they seem to be very experienced at it here. Both parties have to be commited to trying to fix the marriage for MC to work. In DB'ing one person can work on the marriage by themselves.
