yea i think if a girl is flirty and nice she is hot...i have crushes on 3 girls that are sorta like you...i know thay are just being nice but i cant help the fact that i get to be so close with them...if you dont want them to have crushes on you just be upfront and ask them who they like...most guys will name girls other than you and then you should know that they LIKE you but nothing more...if they include you then they WANT you to know that and you need to tell them that it wont work...
