Could it be love....?

i was infatuated with this guy since 2nd grade (yes 2nd grade lol) anyways... i'm in 10th grade now and still cant seem 2 stop thinkin about him. i get crushes on other guys but at the end of the day he's wats on my mind...we were together for a while but we broke up because he moved... we were together for 3 years... and i just wanna know... could i be in love with him?
