Is it normal that i can't have a boy who's my friend cause i think i might like

I can't have a boy who's a friend cause I think there could be more. Any boy who ends up being a close friend (just friend) , I think we could be more. I have had this problem ever since 5th grade ( Middle School ). Most Of Them back then got told that we are boyfriend and girlfriend but we weren't and it freaked them out cause they wanted a girlfriend they liked. So things just became more akward between us , and I just carried on and found new friends including (boy) friends. It is not because of these events that caused me to have this problem, is it even a problem? Do other people have it? This Probelm is like when i talk to a boy who is my friend there are some who I would NEVER go out with but I still flirt with them , and there are some who I think like me but I never ask if they like me. ( some liked me and ask me to go out with them and I said no because I didn't want things to because I don't want it to be awkward between us , even if I like them) IIN?
