so I'm just wondering if the reason guys choose a less attractive girl over an obviously hotter chick is because they're afraid that the more attractive girl has other options and would cheat on them...?
OK so, questions about personality aside, could that be ONE of the reasons?
Well personality aside, I've always followed that same rule. I think the really good looking guys generally are heartbreakers because they are hit on all the time so they are always tempted for something better. I never date too goodlooking of a guy.
Because looks aren't everything and a beautiful girl can only hold a guys attention for so long. If she is dumb as sh*t then eventually the guy will be driven crazy. Love isn't as simple as good looks.
It's also possible that who you consider "hotter" isn't who he considers "hotter." Everyone isn't necessarily attracted to the exact same thing, regardless of what they might say on TV.
Could it be one of the reasons? Of course it could, but you can't know without being inside his head. To be honest, I would doubt it, though. I don't think most guys are worried about their girlfriends cheating on them, because, statistically, it's much more likely to be the opposite way around.
