i'm in the same position, only i'm the girl. this is what i have to say: all i wanted was the truth, and when he didn't give it to me i went off the deep end. he finally told me that he still sees me as a sister, and i was cool with that. so my advice would be to tell her the truth. that would more than likely be what she wants to hear, and if you don't it could be disasterous to your friendship.
