The ten year crush/lust/love/obsession/infatuation

I will try to make a 10year situation as small as i can in a nutshell....

With key sentences

* met him new years eve i was 13 he was 16 love at first sight i felt like it was just him in i in that minute

* crazily never spoke until i was 19, my friend convinced me to hang out with him she would be there .. few weeks go by its almost thanksgiving .... Im shy so she tells him i like him, he says...

Shes beautiful and smart, but he was trying to get over a 4 year relationship...

* month passses christmas time, hes shy so he lets my friend know he had to get something out of his chest , he said he really cared and liked me, but didnt want me to move for college he couldnt take another long distance relationship

* week later things change he starts going to the club and we never again really speak

# flash forward 4 years and im 23, in college(i never moved out of state just a few blocks over ) i have had a serious relationship in between and dated a bit.

Im scared i will never like/love someone . Im scared my mind and heart feel hes the one. He just got in a relationship moving fast, they moved in together and all... I know we arent meant to be, i have tried so hard to forget him, i cant. Help pls tell me u have had a similar situation...
