I would be tempted to go to my W and say "I would like to look for a new MC. I don't like the way this person approached our situation, what about you?" I can't see this going anywhere with a MC who lays down the law on the first session. He or she may be absolutely right about the A and the need for it to end but, geez, you both know that already! Or maybe you could tell the MC you are (as a couple) interested in discussing the "symptoms" and "tasks" to be done and not the A! If the MC makes her feel horrible, your W won't go and really why should she!What do others think here? Also I would agree with Ford, don't give her permission or lie for her re the A. I once thought I would just give my W permission to carry on as she wished (hoping she'd burn herself out with the OP). I didn't want her to resent me as somehow keeping her from her "soulmate" but the C I see advised me not to do so. C said "You have told her what she is doing is immoral, how can you now say it's OK? What do you tell your children if this comes out? That dad said it was OK?If she wants to spend time with OP let it be her decision". My W also asked me once for permission to stay at OW's and I said "Don't ask me for permission because I can't give it. You are free to do what you choose but don't ask me for permission". She did it that once and has never again. Anyway, just some thoughts for you to ponder. Remember, try to look for the good in this day, there is plenty of it if we look! Stay well.
