Why?

Why is it that when I do not feel anything for a person, everyone thinks that I am not trying at it? It has become royally frustrating. I do not have any feelings for this girl who happens to like me, and I think that she is nice. But, we are not really compatable.

I am being told that I am being picky. I do not think that I am. I just do not want to lead her on into believing that something more can come from us hanging out.

It just causes my head to want to explode trying to deal with people and this situation.
