Agree, this is the core issue.
If he loved you, your health and well-being would matter.
You don't, so it doesn't.
The number of women I know that realised this when Covid hit, is very sad.
A few divorced, but not all.
For some it really didn't suit them to, for a variety of reasons, great housing, great location, family and grandchildren.
But have they radically dropped the rope!
They no longer cook, nor do laundry.
The never went back to sharing a bedroom.
They holiday with friends, sisters and took up activities like bridge and are out of the house more than in.
Of course there was pushback.
They were told by all means to instigate a divorce if they want, but there will be no bending on this new living arrangement.
Illness over the past couple of years has been treated as a them problem.
It is a horrible way to end up in your late 60's and early 70's but their bank of giving constantly is empty.
Funny how Covid gave them that final clarity.
They certainly will not be doing or expecting caring duties.
Wider family are aware of the new "living together but apart" dynamic and have accepted it without many questions.
They invariably know that their fathers weren't very caring men, increasingly so, as their mothers aged, expecting kindness to be all one way.
I see in my own circle of women in their 60's, investing more and more in their network of female friends as they retire and make preparation for the next stage.
