I dealt with that in high school.  I was athletic, toned, and in best shape of my life. Swimmer. Girl wanted me no matter what or who I was with. I spent 3 years of my High School life avoiding her and her attempts to woo me away from my high school sweetheart, who was a size 0 and a runner.  She just could never get it through her head that I wasn't attracted to her because she was so fat and unhealthy.  She was one of those crazy girls who falls in love with a guy and thinks they are together when in reality I only was ever nice to her because I was a nice guy in high school.
