I'd like to point out to the "nearly all the good men are gone by 30" posters that - to be accurate - yeah, a lot of men are with long-term partners by 30, but how "good" all those men are is another question entirely!!
There is a suggestion that any who are not "good" end up back on the market; that's extremely naive & unrealistic. We all know women in dysfunctional, unfair and verging on abusive relationships - which are long term and do not break up.
The women just put up with it and lots of platitudes about men "just being like that" are thrown around.
Off the top of my head, I had my hair cut by a hairdresser who said about her partner and father of her kids that he would spend hundreds, if not thousands out of their relatively modest budget on designer clothes and fragrances etc for himself.
That in contrast she would much prefer to ring fence major money to spend on their sons, to see them have nice experiences. She didn't get that chance though - because he didn't give a fuck and kept spending it on himself. She concluded "it's just men though, isn't it".
I refrained from saying "no, it's not men".
That guy has had a partner since young and she has not he slightest intention of leaving him, yet he is not a "good" man.
Another one off the top of my head; re. my partners acquaintance - together with his wife from 20s or maybe even teens - she is conservative and somewhat religious, she won't attend eg Ann Summers type parties with her friends due to her principles; meanwhile my h tells me that he, on football trips, pretty much lives in strip clubs, behind her back obviously.
Another man "taken" from 20s and who has not and will not be left by his partner/wife & end up back on the market.
My acquaintance's h saw most child rearing as women's work and on one occasion- when I was visiting her, she dared to let his DD go out to hang around him while he was fixing a vehicle in their garages, he got into a car and sped off at high speed, spitting gravel everywhere in a temper. I said immediately "he must have the wee girl in the car with him, he wouldn't do that around her if she wasn't in with him, no way, would he? The DD was not in the car with him. He felt driving like that around a child, as well as showing such anger again having her out with him - was perfectly justified.
My acquaintance has not and will be er leave him. To the contrary she knocks her pan out being the main bread winner and being mother of the year.
I could list similar examples all day. And I'm sure every poster on this site could too.
So let's stop with the "all the good men are taken by 30 and only shit ones will be on the market/back on the market" schtick.
There are plenty of shit ones "taken" and not on the market too.
