I need advice please :( i'm a total jerk and i need advice on what to do?

i've got a story that goes with this if its ok...: k so i'm 14 and so heres my story...for about 6 years I've liked this boy who used to be my best friend but then he ditched me and our other friend once we got to middle school. but even throughout the 3 years at middle school i always thought of him like everyday.. Then all of a sudden i meet a new guy while hanging out with my friends they introduced him to me and we kind of have stuff in common. I meet this guy for one day only and i suddenly realize i really like him. and i completely forgot about elementary school boy. anyways a couple weeks l8r from me meeting him, i've been talking to him online and he asks me out. So he's my boyfriend now n stuff..and anyways i dont see him much at all ok? haven't seen him all summer lol. and Highschool open house was yesterday and i saw elementary school boy. I couldn't believe it was him. and my face turned red, i spazzed out, and i was like "omg hide me" and he ignored me which i guessed since he probably stopped being our friend cuz he thought we were losers. but my point is. i don't spazz out like that unless i like someone. but i didn't like him when i met my boyfriend so what the hell!??! :'( and if i do like him then i'm a b*tch because i have a boyfriend who i like a lot and he likes. Sure i dont see him but it's not right to like someone else while in a relationship! What do i do?! Do u think i still like elementary boy? and if so....what do i do with my boyfriend. I like him so much :(
