Relationship Help!!!! ASAP!!!

Hi So Ive been friends with this guys for almost 2 years and at the beginning, at last, school year we were talking for 6 months and short story short he ended the talking and decided to be friends and I went along with it but I was REALLYYY HURT because I liked him A LOT. Now he likes me again and I thought I like him again but now im not so sure im confused if I like him for sure or if I just like the idea of him or if I do like him and I'm just protecting myself from getting hurt because I'm not putting everything into it because Im watching myself how much I put into this. He's my best friend and I would do nothing to hurt him and I dont want to loose him and it doesnt help that my other best friend said that he likes me too and I dont want to loose or hurt either of them... What do i do? I think I like the guy that I liked before but Idk and I need help figuring it out and I also need help on how to tell him how I feel and how I don't wanna get hurt again...?
