A few people have mentioned that the women in happy relationships with men won't come onto MN to speak about that. True, but it's also worth noting that it goes both ways. The complaints we see here from women, about men, are just the tip of the iceberg. Not every woman experiencing some brand of bullshit is on MN, and even if they use MN or other online portals, they won't all speak up. As we also know, women are very good at minimising the nonsense they have to put up with because the alternative means saying it out loud... then probably not being able to ignore the reality of their awful relationship quite so effectively.
Those who really are with one of the good ones, and by a good one, I'm not talking about Mister Bare Minimum Man (because these seem to get lumped into the same 'good ones' bracket too), are in a minority.
Most of us will not find the love we desire from a relationship with a man, but the danger is that as women we are often incredibly proficient in making excuses for men and contorting ourselves into various shapes to kid ourselves that "we're working through it", which usually translates as "he fucked up, I'm compromising yet again, he isn't changing at all, but I will be manipulated into taking a portion of the blame for insert awful incident and then I can make it work".
A good friend once said to me, "I'm no longer fixing what I haven't broken. Instead, I'm letting it fall apart". That's always stuck with me, and towards the end of my dating days, I lived by that until I realised that every single relationship or dating experience is another brief season in life that I'll inevitably have to call time on. It was pointless.
For those with a genuine unicorn, you are very, very lucky. There are not enough to go around for all of us.
Many of us, once we get to our 40s and beyond (and for some women who are far more savvy than I was when I was younger who reach this point at an earlier age), we make peaceful lives for ourselves as singles. I'm absolutely with you, OP.
Wasting time on trying to find that unicorn feels like a terrible waste of time; there are friendships to enjoy (incidentally, my friendships with women have always been full of joy, sharing, generosity, empathy - a far cry from how it feels to be with a man), hobbies and careers to delve into, a peaceful home to relax in, and lots of other really lovely things in life to create a great and fulfilling life.
