Basically, if she wants to fly away - it has little to do with
looks. I have good looking friends and they are reasonably
faithful. I feel that good looking or not good looking is a choice
and effect of self-confidence. Those who are confidence of
themselves would attempt to go for anyone they fall for, even if
she is pretty. And even if she is pretty, they wouldn't treat it as
a barrier factor. 
In the end, it all
boils down to the fundamental basis of love. Loving yourself first
and knowing what you want to get (I. Physical attributes, II.
emotional requirements, III Misc.)
Cheers
