I know this hurts, I've been there. You can't help her with this. The best you can do right now is not talk to her except about your son at pick-up and drop-off.

Detach, detach, detach. You've never really detached, at all. She's never had the opportunity to be away from you and heal.

Hang in there.

Let me give up the need to know why things happen as they do.
I will never know and constant wondering is constant suffering.
