Glad you had a good Thanksgiving. Detaching does help as you have already seen in a short time. It will be hard, but you really don't have much of a choice.
Regarding MC, maybe I forgot to mention this before. Are you both in IC (individual counseling)? I wonder if going to MC right now is a bit on the early side. One of the reasons there are M problems is that one or both people are simply unhappy. Sometimes it takes IC for one to help them figure out some things before MC is beneficial. I guess the fear is going to MC too early and W just saying "see we can't get along, this isn't going to work, blah blah blah" It sometimes fuels their decision to leave. I never got an opportunity for MC, but I wouldn't have went just after the bomb - because I needed IC first. Just my opinion. Just assess the MC as is it helping or it is hurting. Too early can be a hurting factor.
I hope it goes well with you. I'll check back in later.
