I like this guy and its complicated?

Ok so Ive known this guy for years scince the 3rd grade and i am now in the eight grade he had a crush on me at least in the 3rd and 4rth and 5th grade but he asked me out three times and the last time he asked me out i thing i might have really broken his heart he was really into me and i tricked him i said yes as a trickn i was gonna dump him later that day but my bff lied and told him i was gonna diump in front of the entire school which i wasnt and i nevver liked him then.He moved away in the fifth grade not because of me because of his family and he came back to the my school destict this year eight grade and him and a friend of mine dateed but she dumped him for no good reason and he is really sweet he always has been I almost fell for him right befor he left but he wasnt there quite long enough and i dated this guy that used to be one of my bffs and this guy that i like knows that and i dont think that amtters but its tru I dont know what to do its cofusing this other guy i fell for it took me several years to trust him but the guy i like has only been back in my life for a couple months and i feel like i can trust him already and trust is a huge thing for me
