Does she like me as a friend or as more than a friend?

Awww!! You two sound adorable together! Is SHE a or bi? I think knowing that first would be ideal so you can maybe feel a bit more comfortable telling her that you are. And you said you have been friends for two years and she doesn't know you're ?? Maybe she already knows you're gay but doesn't want to bring it up because YOU haven't yet. And yes, it does sound like flirting to me. It sounds like you both need to talk to each other. A REAL talk. It just sounds like you both are nervous about what might be said, or fear or rejection. GOOD LUCK to you guys!!
