I second this. Your husband and you are independent and functioning fine. It's normal for him to feel some anger and wistfulness over this twisted family dynamic, but as an adult we just have to accept, separate, and move forward. There's nothing you can and should do about how things are between his parents and his sister. Just be glad you and he are more healthy than that. And think ahead and talk with him about what it teaches you regarding how you'll treat your kids and what you'll not expect from their paternal grandparents.
