Towards the end, before I left, I said to my wife, "if you want to live with your parents forever, then you shouldn't have a husband." To which she instantly replied, "GO, THEN!!!"
I think she was trying to recreate her own childhood after her mother abandoned her and the family to pursue a career. She just up and left in the middle of the night without even a word. My wife did the same to me.
And it's the worst kind of selfishness when she thinks she deserves to have both her parents with her, but her daughter doesn't deserve to have both parents.
