A Girl Likes Me But I'm Not Gay??

Lyn • Single from the womb to the tomb
I am doing theater, and one of my friends pointed out to me that one of our queer friends was getting very touchy. I'm a touchy person so I just thought she was being friendly. Also I had said as a joke to this girl "If I was gay, I'd be gay for you!" And she's always touchy feely, and lets me put my feet on her legs between scenes and is always complimenting me and gets me my favorite food and she's a sweetheart and then one of my other friends said that this girl told her she was crushing hard on me. I'm not gay and I don't know what to do??? I value our friendship but I also have a boyfriend? I've always been very expressive on how I support my queer friends and how I don't judge queer people but I don't know what to do.

We called each other and we talked and everything is fine now! We are hanging out tomorrow and everything is fine, thanks to those who answered!!
