My gf is nearly perfect, but she’s too dumb to be with.
This is sad. I know I said I’m an elitist. And I am. That reiterated adequately, there is also nothing wrong with being dumb. It’s usually not much of a choice. However, there is something wrong with being a dumbass. The girl in question is not smart, but she does not sound like a dumbass.
The guy would very much be a dumbass, though, for staying with her. He’ll eventually get annoyed and treat her poorly, and she doesn’t deserve that at all. Dumb people should have good lives too.
