Most Helpful Girl
Well of course looks matter; everyone has a type they want. But I don't think it matters more than personality. There's only so much of a boring lame personality person you can take, before you go looking else where, no matter how hot they are.
But on the other hand, my best friend was dating this guy she really wasn't attracted to because he was so much fun (super awesome, miss him a lot actually T.T ) but the relationship hit a brick wall because she couldn't bring herself to kiss him.
So, they both play a pretty good part in choosing a partner, but I'd say after about 30 years when the both of you are looking like who did it and why, personality is what triumphs :D0
