>>212370261 (OP)this logic universally applies to bad boys vs nice guys, not just X ethnicity vs Y ethnicity.
even in my monoethnic country, it's common for girls in early 20s to date tall handsome but deadbeat guys, then in lates 20s/early 30s settle down with nice guys with stable careers.
i've a female friend like that. in uni/20s her boyfriends were all player-type pretty boys. at 29 she married a balding manlet nerd who has a $$$ salary.
