I've been disliked by males (in a romantic sense) just about all my life, and people tell me that it's because they are "intimidated" by me--they tell me that because I am smart, good-looking, and confident, it scares guys away. I don't think that's true, but if it is then it goes along the same lines as your story.
p.s.
unlike that cheerleader, I discovered that statistics is a lot more satisfying and fun than men. I treat them with the same indifference that they treat me, and sometimes I end up having purely platonic guy friends. in short, I learned to like myself even though other people don't, so I didn't become an alcoholic.....
