Here's the story. I liked this girl, she was intelligent, pretty, etc, and we were fairly good friends beforehand, but now that I've found out that she has no interest in me, I completely dislike her, and I don't really understand why. She's the same person as she was before, so I find it hard to grasp why I no longer like her even as a friend. Perhaps I resent her for not liking me, even though I told myself, "even if she isn't interested, you still want to be friends with her." It's an odd feeling.
