Most Helpful Girl
It depends on the girl's attitude. Looks can attract all types of people; jerks and the good guys. The girl can use her mind to have better discretion on whether a certain is good for her or not.
If the girl is beautiful and is completely self-absorbed, most probably she will be crushed in relationships by jerks because they know how to attract her attention which is by complimenting her all the time, buying her sweet and expensive gifts, telling her how beautiful she is all the time and whatnot. She feels so happy at first but then the guy's true colors show and she understands how stupid she was. If she is a wise girl, she will start to expect actions rather than words from guys. If she is shallow, she will never understand.
A beautiful girl may also intimidate the nice guys because they would think she is high maintenance, shallow or self-absorbed. People are judgmental, you know, and think "beautiful"= shallow which is completely not true. I have met average looking girls who were totally shallow while other good looking girls who were humble, extremely nice and not intimidating at all. Anyway, gorgeous girls may compel nice guys too. Jerks are courageous and appear so brave so they don't get intimidated.
All in all, when girls grow up and mature they understand how jerks think and how to avoid them at all costs :)
