Good luck with the MC. My H and I have been to 2 session so far and I am yet to see where he is with this marriage. He is the one that is having the A but is still willing to go to MC. Take that as a good sign but do not expect too much to come out in the first session. It will be more of the MC getting to know your sitch and trying to get a little info out of you. Good luck and will keep you in my prayers.
