Apologies in advance if his becomes a long brain dump, but my head is all over the place and I don’t know what to do.
My sister is a very tricky character; she is aggressive, a pessimist, a perpetual victim and just seems angry at the world. She also has many great qualities and we have a solid sibling relationship. However, she has real grievances with my parents stemming from our childhood. My dad was one of 7 boys and his mum always made it clear he should have been the daughter she longed for. He never received love as a child. He can be controlling over my mum and his personality is what I would describe as a mood hoover; when he’s having a bad day we all felt it and walked on eggshells. My mum was abandoned by her dad when she was 15 and her mum favoured my aunt. I think it’s fair to say she has classic “daddy issues” and that’s why she has put up with our dad for so long.
Our childhood was tricky. We wanted for nothing but our parents both struggle to show us love and we grew up knowing we lived in their house, it was their life and we lived in it, etc. Now I’m a parent myself I understand my parents a lot more and am desperately trying to break the cycle when raising my own children. My parents are truly wonderful grandparents (way better than they were parents) and I have forgiven the mistakes they made when we were kids because I recognise they were doing their best.
My sister however cannot and she recently confided in me that she intends to go no contact with my parents. She hasn’t said when but she’s currently buying a house using deposit money gifted by them and I doubt she’d risk that by going NC now.
I’m finding the burden of this hard to bear. I want to warn my parents because they will be heartbroken by this and also to give them a chance to try and fix things. But I’m also not willing to break my sisters trust. I have always been the go-between when they (frequently) fall out and I hate it. I’m the youngest in the family and have children of my own to worry about, and all this is affecting my mental health. If my parents find out I knew they will be furious with me. I lose either way and part of my family will be wrecked.
Truly, what do I do?
