@whowouldathunkit: I think things aren't helped by the whole "Eat, Pray, Love" movement. I know of a lot of men - myself included - who were told they were good men and dads but got dumped because of the message that if a woman is bored that's a good enough reason to break up a family - because you deserve it! Not work on it. Not recognise that butterflies never last. Junk it because you deserve something more.
And while I'm sympathetic to the notion, it places a bind on men who were raised to be more caring, sharing types - those men who were made aware of the likes of Shirley Valentine and swore we'd be different. Because you feel now that nothing you ever do will ever be enough. I'm only human. I'm going to have faults. I wish I didn't but the best I can promise is that if I'm made aware of them I'll own them and try my best to improve. But look at Elizabeth Gilbert herself: even finding her True Love at the end of the book/film didn't stop her from divorcing him a decade later.
The reasons? "Love is complicated". "Soul mates are here to teach us things not to last". Well, I'm sorry but those complications tore apart the lives of a lot of people. I absolutely don't want that to happen ever, ever again. And a lot of men, from what I see and read, feel likewise. This isn't the toxic "red pill" stuff. It's nothing to do with women "knowing there place". Just a simple sense that you could try to be the best man in the world and still the person you committed to could throw everything away because they're bored or need to find themselves. And, for a lot of men, that can be a very high price: seeing their kids only every other weekend, having to leave the family home for a rented flat. That stuff is soul-searing if your a man who's grown up wanting to be a "new man".
So I think there's a trend with some men, being told online this is the way of things, to weigh things up, think the potential cost is to high and the stakes aren't that good and instead opting for casual hook-ups instead. It's commitmentphobia, for sure, and truth be told I think it's very sad.
