If a girl asks me why I get nervous around her, does she know that I like her?

A girl i kind of know, but very little, was talking to me and i have a crush on her.

she must have noticed that i got nervous, and she asked me why i get shy and nervous. After that she asked me if i have a girlfriend.

does she know what’s up?
