You're right, but the bigger picture is that the OP is about to seriously consider using a sperm donor. A 60 year old man with good genes who will provide 10 years of active parenting and an inheritance for the kid is a lot better than a sperm donor who will provide nothing. As for looking after him in his old age; she should screen for 60 year old men who can fund their own old age care.

This is terrible advice. This means that she would likely be widowed before she is 60 and will either have to start dating again or be alone in her golden years. Also, it doesn’t matter how good his genes are because sperm quality degrades with age and can cause birth defects.

I think you're letting perfect be the enemy of good, which is how the OP got into this mess.

Obviously it's best to meet when the woman is 28 and the man is 32. Then have kids when she is 31-35. The OP didn't do this and is now a bit stuck.

The OP is no longer able to attract the men she used to so she has to find a compromise she can live with. Older men are an option, ugly men are an option broke men are an option. The men she wants are choosing women exactly like her, but 10-15 years younger

Probably she's going to pick the default which is no kids or use a sperm donor.

The problem isn’t that OP isn’t getting anyone around her age who is interested in her it’s that she is rejecting them. I’m not saying she gets perfection. she is out of time to look for a Disney romance and having a family, she gets one and just needs to settle on someone who is likely also settling for her.
