Not the only criteria.
Basically here's the thing. About 3 years ago, I answered an ad on match.com. This girl was cute, about 5'10 and a half, a South Park Republican type, total 80s metalhead like me, basically the PERFECT girl...but...she flat out told me "I am sorry, you're a sweet guy but I just can't be with a short man...I just can't find you attractive." Ever since then it's been a sore spot with me, since I can't do a damn thing about being short.
She wasn't worth it in the first place...good thing you found that out early.
She said that to you on a first date? Are you sure that was the real reason or just one she made up?
Guess it didn't occur to her that it makes no difference when you're lying down. :)
