How did her friends know that i liked her?

[iamgoodboy]

I'm the kind of person who keep my secrets to myself. So I kind liked this girl, we talked alot, we're often drawn too each other, we text alot and if we go to the movies along with my friends and her friends we would always sit together without saying anything. SO lately her friends keep asking me if I liked her.I dont know how the knew I was like completely shocked and if they ask me i dont know what to say.I dont want to say yes cuz there's a chance that they will tell her also I dont want to say no because if they tell her that I dont like her, she might feel bad because I have a feeling that she likes me too. SO WHAT SHOULD I DO??

Grow a pair and make a move on her. And tell her nosey friends to butt out.
