grrr im stupidd

so I went out wit this guy from 7th-8th grade. we lasted about 9 months. he broke up wit me and went out wit one of my friends a few months l8r and then went out with another 1 of my friends. soo I nvr really stopped liking him…lk ever id always say I didnt,, but I really did. and every once in a while I will tell him “ohh I lk you again” eventhough I nvr stopped lol. but hes just not interested and I guess im ok wit that,, because I kinda have 2 b. I was almost over him. but last night I went over his house because our fams are friends. and I was talking 2 him and I started 2 lk him…AGAIN. and 2day I was talkin 2 him on aim and he told me he was going out wit this other girl. im effing pied at myself for letting this happen 2 me a third time. he does a lot and by a lot I MEAN A LOT of a holeish things,, but it doesnt phase me. I seem 2 look past everything he does that makes me mad.. am I lk obsessed wit him?? no idts,, I just can’t seem 2 let him go. and even when I lk someone else…its short lived

sooo my question is…how do I turn myself off 2 him??
