I've had a major falling out with my oldest friend, the result of years of resentment. I've decided to cut all contact with her for my own mental health. But I still love her parents. They're like my second family and I'd hate to lose them. AIBU to think I can still maintain a relationship with them even if I have nothing to do with their daughter anymore? For context myself and friend are both late 30s and she doesn't live with them.
