My dad has one brother. Both met their wives when they were all teens and are all still married now. Dad and uncle have a very explosive relationship and regularly have major bust ups and fall outs. Neither marriage is happy. Mum and auntie (related by marriage) have sustained a near 50 year friendship throughout this and have never let the (very difficult and unpleasant men) impact their relationship.
My dad and uncle had a major, major falling out about 2 years/18m ago. I have no idea what happened but it in some way involved my cousin (uncles son) and following this, my mum stopped hearing from my auntie. After about 6 months, my mum rang my auntie to see if they were still friends and it turns out my uncle and dad were involving cousin (male, 40s) in their arguments and it was taking a toll on cousins MH. as a result, auntie went NC with my entire family - though she did not say this explicitly. When my mum called, auntie expressed relief that they could stay in touch and they had a great talk, and said she would call.my mum soon
... but never has. My mum understood and respected that auntie is just looking out for her son but I know she is hurt That she is collateral damage due to the behaviour of two grown men.
In the past year, my mum has been diagnosed with stage 4 cancer and may have only between 6m and 2years left, depending on how palliative treatment works, but honestly she isn't fully cognisant of this and still thinks they will be able to cure it. She has said she wants as few people to know what's going on as possible as she's embarrassed at how ill she is and wants to get better.
My AIBU - should I tell my auntie what's going on and give her the opportunity to call.my mum 'out of the blue' and reestablish their relationship while.mum is still around? I want to be respectful of both of their boundaries, but I have a horrible feeling my auntie will be left feeling regret. Although I run the risk of overstepping by contacting my auntie, I worry that not giving her the opportunity might also hurt her. It also.makes me sad to think my mum is dying and thinks one of her oldest and closest friends doesn't care about her. If auntie declines to make contact, mum is none the wiser and I have a clear conscience.
YABU - NC is NC, keep out of it
YANBU - surely she deserves to know so she can make an informed decision
