The female dating coach Logan Ury wrote a book called "How not to die alone" which discusses this issue.
Women set expectation bar so high, only top 5% of men meet.
This seems like a rational decision to me. Better go it alone than risk becoming the sole carer of both a baby and a man-baby.
For example, being over 6ft doesn’t make you a good dad. Or being physically attractive, doest’t make you a supportive partner.
If anything, these characteristics make a man worse, as men in these categories tend to have the pick of the litter, resulting in many women frustrating and disappointed in men if they weren’t selected.
Men in their 20ies don't want kids because they still want to enjoy life without responsibility, but by the time they are in their 30ies they are ready to settle down and the idea of having a family becomes more and more appealing.
I don't feel as though I wasted any of the "fertile years" of my female partners who ended up not wanting to marry me!
I had a couple of different long-term relationships in my 20s before I found a woman to marry and start a family with, which we did just fine in our 30s despite having two miscarriages in between kid #1 and kid #2.
Anecdotally, I see many women who want to settle down but never take the initiative to ask a guy out.
This does not make sense. It's not men taking birth-control pills, plan-b and having abortions.
