There was a very pretty girl who sat next to me in English class in high school, who I had a crush on, who grew up in an upper middle class family that was going through a terrible divorce.

Last I heard she's a professor of the Quechua language in Hawaii and lives alone with a large dog and has probably aged out of her fertile window. I can't prove that her family's divorce had anything to do with the trajectory of her life and her not reproducing, but on average there is a correlation.
