Hi and welcome,
Try not to feel guilty about the po's wife. It isn't your fault. It's her husband's fault, and the organization's fault in the end, the leaders of it.
They try to blame everyone else. I hope you begin to feel better about things soon. So sorry about your daughter being shunned. Me and my oldest daughter are now being shunned by my younger daughters, who are 25. It's so frustrating, sad, painful, aggravating, well, you know.
