I've been divorced from Ex for over 40 years.
Many years ago, my daughter (now aged 48) fell out with her mother (my Ex) over a trivial argument. Despite many attempts from Ex, my daughter has had no contact with her mother for over 10 years. Likewise, the three grandchildren have no contact with their grandmother.
I've just heard that my Ex has cancer; she has had a lung removed, and will be having a mastectomy soon.
So, here's my question... shall I tell my daughter, and give her the opportunity to reconcile? She has made it very clear that she never wants to see her mother again.
