Many women have been so indoctrinated by the feminist movement that they aren't worth being a mate with a man. A man can see it clearly so why should he make his life miserable?
Yes. I've been happily married for years -- but I've worked with a number of young(ish) women who were "trying to get married". And I just looked at them, and listened to them, and thought, "It ain't ever gonna happen -- unless you find some guy who's really, really dumb."
But these women don't seem to have a clue -- they think they are the best catch on Earth.
