FYI, at the point where my H had just broken 2 months of non-contact with his OW (not that I had any way of knowing this, except that his behaviour became a lot more up-and-down) and was talking for the first time about possibly leaving the house and talking about how our relationship was unfixable, I was the one to find an MC, make the initial calls, set up the appointment, etc. I'm sure I chose better than he could possibly have done at the time, because a depressed person is almost incapable of making decisions.
The next 3 months were hellish for me, but in retrospect I can't believe how much progress my H made in that time because of being forced to work on his issues by the C. No matter what happens in your marriage, that work would be invaluable for your children.
I remember 3 horrible Christmases in a row. But you know, after that they've just got better and better--hang in there, and make it the best one you can for your kids.
