I'm really confused about guys can someone help me please?

okay so i really like this guy we'll call him guy 1. i've liked guy 1 for like 3 years and i told him how i felt and he said he liked me too but wasn't looking for a relationship so i said ok i'll wait but its been quite a few months now and we still talk but he hasn't mentioned anything about it. Now guy 2 just moved here this year and we're like best friends and he just asked me out. i told him to let me think about it cuz like i said i really like guy 1 and i think dating another guy might lesson my chance of dating guy 1. also i don't really have feelings for guy 2. then there's guy 3 who i almost dated i really liked him over the summer but got over him because he had a gf.. but know he's single and asked me out. i also asked him to let me think about it because i would go out with him but there's guy 1 he'll find out and then he may get a gf and not want to go out with me ever!? im new to this whole thing in in 8th grade can someone please help and please no "you're too young focus on school" thanks!
