Being a lawyer, that would be her default position, but I wonder if she really would want all the responsibility. It might mean having to cut back some on work, and she seems most devoted to that. So I was wondering just how joint custody would affect her.
My wife would absolutely hate having to split time with the kids. She could learn to adapt, but she would hate it and I think that is her biggest fear. I you can't have a spouse who regrets a failed marriage for her own sake, then I suppose having a spouse who hates losing the kids, at least part time, is the next best thing, as far as deterrents to divorce go.
