You men aren't avoiding marriage, young women are. If young women wanted to get married before having sex, and demanded that husbands have their own place and a job, guess what you would see going on in the world.
What society has done instead is to stretch adolescence out to the age of 30.
I think it’s the guys.
I have a beautiful, size 2, 20-something who has a degree, highly fluent in a second language, very well read, internationally experienced, sensitive to the needs of others, creative, good cook, sews and crochets, artistic and talented in calligraphy, writes novels, loves and adores children, extremely nurturing, optimistic and joyful, and lifts the people around her and deeply loyal.
And cannot find a husband.
She’s the kind of girl a guy needs to marry, and they want the high maintenance ones that they should only date. She gets thrown under the bus because she’s “too good” or she won’t get serious after 3 or 4 dates. It takes her a little to open up and that seems to be unacceptable. Gotta be a sex kitten.
