Anyway I guess I had hoped to hear from XWs about anything that might have helped make it easier.
Not an XW, just an XD, but I don't think there was anything anybody could have said to or done about my mum to "make it easier". She broke into a million pieces in her 40s, the day dad left. That was the mid 80s
My sister says that since learning of our father's death a few years ago a change started, and recently she's been more similar to the mum we used to have. Time will tell if that'll last, but possibly not much time cos she is dealing with a significant illness. I hope she finally does get some peace. At least one of them getting some would be better than nothing.
I think what my father & his now widow didn't factor in is that we all get to make our own choices, but they don't include our preferences in terms of other people's reactions to those choices. Nor how long they will last. And no amount of wishing it were different will make it so if the other person feels (justifiably or not, depending individual opinion) destroyed, abandoned and angry.
Personally, having lived through that kind of dynamic on the child side of the equation, I'd run a million miles at warp speed nine from anybody lugging similar looking baggage into the latter part of my adult life.
