Oh, I hope I'm not too late. You mustn't confront this girl again. She's already told you how she feels, and suffice to say, she's not that into you. She may be confortable with you ,because she views you as her friend. It's safe to flirt with you(she might actually be doing that, or you are reading more into nothing), because she knows the friendship protects her. Trust me, I know of what I speak. I tend to come off as flirty around guys that I don't actually like, because I'm comfortable. They are either friends or guys that I'm just not attracted. Thus, I act like my regular crazy self. I clam up around guys that I do like. I fear that if you talk to her, she will blow you off, and you might lose the friendship. Are you willing to take that risk?
