Do you people here understand what an actual healthy, happy family is all about? It's not about blocking your mothers on FB or tearing apart relationships and encouraging women to leave their husbands so they can be as miserable as you.
It is having a support system and living each day. We don't know the future, can't really plan on it. Her family will be fine. All of them. Come what may.
I understand the jealousy. You can attempt to mask it under moral superiority, but it doesn't work. Not at all.
