if she is bi, would that make you feel any different toward her or your feelings toward the friendship... Why do you need know, I suspect you've had some thoughts or maybe wondered about yourself... are you bi-curious? don't worry what other people may think. Focus on how you feel, if your interested in her... it sounds like there are some signals there from her end... Sounds like she doesn't want to make you feel awkward if you aren't feeling the same way...
