do i have feelings for him, what do i do...?

[BrightStar]

this may be a bit long but thanks in advance for answering

ok so there was this guy who i used to talk to. we got really close, we didnt go out or anything but i did have feelings for him them. but we said that were gonna be best friends and not go out. i used to tell him everything and he used to tell me everything. i just felt so comfortable around him

however, what i didnt know was that everything i told him about my life, he went and said all this to his friends. i also later on found out that he was only being like his to me coz he only had one thing in mind, how to get me into bed...
even though he knows that i will never loose my virginity until im married. he tried and tried. i felt so stupid and now live fear in case of what he might do with everything he knows about me.

and then a whole lot happened (fights, arguments ect) and we stopped talking. he blocked me on everything.
but for some reason i cant get him out of head. hes all i think about. my friends tease me about him but i pretend i dont like him. i go onto my old facebook account and look through his profile

do i have feelings for him? is this normal and what should i do?
