I would say accept your fate and when you accept it, you can properly enjoy yourself. Perhaps then a man might turn up who’s right for you, when you least expect it.
I see a ton of divorced middle aged women who when you ask why they’ve divorced say their man was cheating or left them for a younger woman. Or they say their husband was a selfish, useless lump who did nothing around the house, or helped with the kids, living separate lives, totally exhausted.
initially these women get all excited about being free to find someone new, they do this joining clubs, getting out there, dating online, friends of friends match-making.
Then after a while on online dating, it becomes a horror show of men with criminal records looking for money or a home or skivvy to look after them whilst they chase younger women, men already married looking for free sex, men with several women on the go just looking for cheap sex. Weirdos, mentally ill men, men with addiction issues etc. Essentially, all the good men are taken by that stage and the ones left you want to avoid.
Some of these women want companionship, but men just wanting sex or a nurse with a purse.
eventually the more intelligent women just accept life and get a dog as company. They are the women who are fulfilled.
I would add that a family friend in her 70s who is 3 times divorced and very chatty and vivacious went on a cruise and literally brazenly plonked herself at the table of a recently widowed man who was sitting there with his 3 daughters. She started chatting him up, by the end of the cruise they were in touch. She moved out of her home into his home and they live as man and wife, she rents out her home. That’s been going on 10 years. He looks absolutely delighted with her.
another female friend in a 40 year marriage husband died. Within 3 years, she married his brother who was also widowed from his wife, so her nieces are now her step daughters.
in life you see all sorts of unusual set-ups, so I would encourage you to keep an open mInd. Situations can come out of nowhere.
