You might to read SmileyPerson's old threads. He had a detachment & communication technique he'd call "Smile and wave," and I think that's about right.
You have to take a VERY detached, almost bemused, above-the-fray approach if you are to survive this phase. And even then, I don't think one can do it for more than 90 days or so.
I also tried to arrange my schedule such that I had as LITTLE daily in-person interaction with my wife as possible. I was able to cut out about 75% of it, and that helped, a lot. The weekends were much tougher, tho.
