Even if it was a cover, it can lead to progress. I would guess that many people would love to get an easy agreement for MC because they're stuck with a W/H that says I don't even care to try. If she really hated you and like it that way, why would she agree?

Some things to consider with your first MC:
- make sure your goal to save your marriage is her/his goal
- ask how they will ensure it doesn't become an attack on her (or you) because then it may only make problems worse
- ask what you are expected to do if you (or she) get too emotional or angry
- ask if things said in MC can be ever used in court
- show by action your best listening skills to your W; convince her that you are really trying to make BOTH of you happier
- be willing to change any decision (ie quiting job)
- if you start feeling the MC is saying, "wow, your M is screwed", get a new MC

I remember someone saying that they went home complaining about their MC session, but once at home, they felt desire which led to sex. Go figure...
