Looks and intellect don't necessarily decide your dating life though. She's probably had lots of guys interested, but may have wanted to concentrate on her daughter (or been gun-shy since her ex was a cheater). Knew a girl in high school, smart, pretty, great personality. Got married early and had a son. Marriage tanked quickly. Spent the next 20 years putting herself through college and raising her son. Only dated once or twice in all that time as far as I know. Still just hangs out with groups of friends (both genders) and doesn't date. Quite happy.
On the flip side, my brother in law is a fairly handsome, successful, guy. he's on live in girlfriend #5 or 8 or 10 (something like that) and has had 5 actual wives in between all that
He just sort of skips dating straight to marriage or commitment....then finds out later they're bat-shit crazy or wanted by the police
. He never, never, cheats....but meets someone new within 2 weeks of a breakup.
It takes all kinds
