Is it okay..or seem weird...?

I'm a 15 year old girl, turning 16 in April..seems like a teeny bopper question, but I used to have crushes all the time when I was younger..now it seems like..since I haven't exactly had much relationships in high school, I'm sort of doubting it will ever even happen..so I just try and stay away from crushes..like right now I like 1 guy, but starting to not like him, were good friends and all, but just...don't want to set myself up for heartache you know..sort of like..I don't want to crush on anyone, until I know they like me...is that weird, or okay..or what..?
