no you are totally normal! loads of male friends of mine have said they have had crushes on me, and i have sometimes felt the same way back. i once went out with my best male friend but it didnt really work out, and we lost our friendship. when another friend i thought i liked, said he liked me i didnt do anything about it and we also lost contact eventually!! i think sometimes u have to try things, but always try and keeps thing so u can go back to being friends, although its seriosuyl hard and you have to decided whether its worth the risk
