Am i a beyotch for doing this?

i'm a senior in hs and i will be graduating soon. a few days ago, i went to a dance at a diff school (completely casual) and danced with this guy my friend introduced me to. the dancing got pretty hot and heavy and he gave me his number at the end. thanks to a facebook i found out that he was actually a freshman -_- so i deleted his number and whatnot because i was legitly creeped that i grinded with someone 2-3 yrs younger. he friend requested me a few days ago but i am currently ignoring it. i am going to college and starting anew, which is why i am ignoring this/deleted his number, and the fact that he is so much younger doesn't help either. unless i visit my friends in that town over summer, i should never see him again. should i at least accept his friend request? am i a beeyotch for doing all of this, making a big deal out of nothing?
