Help

Im a gay man and I have a bit of a dilema. My female friend of several years came out as lesbian a year or so ago. A week ago she texted me on Facebook, "I don't know if Im really lesbian." I ask, "Why?" She said that she has a crush on me... Somehow i avoided the whole thing and we started to talk about TV shows. But now Im not entirely sure what to do now... Can you potentially help me?
