Does anyone have any thoughts on I how I should go into mc tonight?
KCRoo,
The MC should give you both an opportunity to talk, so let your wife tell her story and you can tell yours. Keep in mind, sometimes MC can go really badly.
My wife (now XW) actually recommended MC, but when things clearly weren't going her way, she bailed (after three sessions). The third session went so poorly that I'd rather have been beaten with a baseball bat.
If your wife is truly on-board and wants to save the marriage, then it'll probably go well. If MC is just another item on her pre-departure checklist, then it probably won't go so well.
