I seriously need advice.

So me and this guy have been dating for almost four years and yesterday i had broken up with him. Dont get me wrong, hes a really nice guy, smart, handsome. But i just cant garner feelings for him the ways hes showing me. More info, i dates this guy when i was 13, i am now 17 and the feelings i felt four years ago are gone. i thought that we could rekindle the fire but for me its gone. So the dilemma here is that, i told him we should take a break and he has been asking me to talk to him and my real life friends just seem to be on his side and keeps telling me to take him back when i feel like if i do that then nothing is going to be solved. I just need to be told that i am doing the right thing for myself because i feel suffocated and trapped being in a relationship. I think with me being biual, im more tending towards girls maybe. idunno
