Do u think this is tru luv? (guys PLEASE answer. girls can to.)?

ok. ive liked this boy named Tristan for about 3 years. last year we were off and on alot. (between me and this other girl.) anyway, i didnt get to see him all summer so that broke my heart. i went out with his friend to try to make him jealous and want me again. i loved it when he told me he loved me and said "sweet nothings" to me. and this year he went out with that other girl but found out she kept going on and off with another boy while dating him. so now they are broken up. and now, since im older (in 8th grade) i developed, u no, and got a more curvy and stuff and he's always commenting about that.(good comments) and now, everytime i see him i melt. my mind turns to mush and all i can think about is him. when i do think about him its just how much i love him. when he says my name my stomach gets...erflys? yeah, i dont want to hurt out friendship. but i really do think this is true love. girls, guys, advice on this please??
