"@Hbh17 If she had planned ahead when she had the chance, she wouldn't be making these demands of you - it was her choice not to do that. And it's a lesson to all of us not to rely on a spouse to always be there, & to develop our own independent lives".
Fgs! Op's mum will be in her late 70's or early 80's at best now. If she had " planned ahead" she would have not only been physic but most likely contradicted all social norms of her time. If she had "planned ahead"
she may well have chosen to be born 50yrs later than she was. All the freedoms and social interactions women have today. were not available to women 50/60 yrs ago.
"@Klippetyklip she doesn’t have many friends. The ones she does have live quite a distance away".
That is what happens when you get old . You move, your friends move away . They then die of old age.
What would like her to do in her old age, join Bumble, MeetUp, Nextdoor? Local community Facebook group?
" I thought she’d be keen for me to nurture my friendships due to her situation but I honestly don’t think she’s thinking clearly anymore".
No, she is not, she is widowed, isolated, lonely, afraid and bereft. Her life long partner, protector, organiser and provider of all emotional support has died. She is elderly and from a different generation . She can probably hardly think at all right now. Your friends will understand if you need to spend some time with yr mum. I suspect her recent grief has not considered your coffee afternoons or your friends at all.
"To be honest I think I just want to vent".
And you have.
