No problem, I wasn’t sure how I came off either, knowing how some of the community can sometimes respond to posts criticising Linux/ranting about real issues, I just thought I’d make sure and clarify my intent.
FWIW, I also hate the flatpak/snap trend btw…
There is no age at which it’s ok to stay in a relationship that makes you miserable. One can fix it or leave it. By the sounds of it, you seem to believe yours is beyond repair. And there is also no age that is too old to experience new love again.
A good friend of mine, about your age, was in a somewhat similar situation minus the religious element. He held as long as possible, until their children were out of the house, at which point there was no glue between them anymore and he filed for divorce. That was a year ago. This summer I met his new partner, and he’s the happiest I have seen him in a while.
That being said, I also have examples of divorced men who aren’t as lucky relationship-wise. Some of them are ok with it, others not so much. I am not saying this to agree with your family, I just don’t want to give the impression I am looking at this with rose tinted glasses. It’s always easy for strangers to give advice, but when actually faced with the situation, it’s another dilemma entirely.
Ultimately, whether it’s leaving or staying, you do whatever is best for you. I sincerely hope you can figure it out for yourself, with honesty, and without external pressures.
