Why do i have relationship problems?

My boyfriend and i have been going out for a couple of months. We really get along but im just to hot for him. He tells me all the time that i have a nice body but i dont think he realizes how good he has it. my life revovles around making him look better in the popularity crowd. But i always seem to overshadow him. I think its because i am the head cheerleader and he is the captain of the chess team. He is also in choir and is in the quilting club of america, he used to be in boy scouts but he got all the badges. I can do all the cool things, i am the most prettiest girl in school and i have dated some smokin guys but dont know there is something special about this nerd. I love him very much!!!! he even wrote me a song about all my qualities. Someone tell what i should do dump him or keep him. Cause there is a much yummier guy flirting with me everyday in spainish even though i dont even know his last name oh it really is a shame. HELP ME!!!!!!!!!!!!!!
