I had read that your wife wanted to go to the MC. Since you've already comitted to go, I would do so. It's sending the signal that you are willing to support her in this. The first time, I would go w/her and if during the meeting you want to get up and allow some privacy for her and the MC, then do so.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
