I feel the same way and, like you said, everything that happens once I walk out that door is on me. So you should give yourself a break. I know you won't, but you should.
SmileysPerson,
I think a "positive", if such a thing during any of these situations that impact children, is that you wife recognizes her responsibility and accountability for what's about to happen.
My wife, to this day (7 weeks since she moved out), even through the court required seminar on Children of Divorce, and her being a child of divorce as well, says that our boys will be fine that they will not be impacted.
Even when she calls to complain how they act up now when they are with her, like they hadn't before, and ask to go home to Daddy, that she can't see how it has anything to do with this situation.
She had even wanted to tell them first on the day after my son's 7th birthday, then she proposed Easter Sunday. Saying that they will not remember that day as it she doesn't remember when her mom told her so it's not that big of a deal.
At least your wife is seeing her children through the fog. Be thankful for that.
Hang in there
