Why does she keep pushing me away?

So the story goes!:

Me and this girl Allison were talking for like a year, and we were 'talking' day and night for hours. I finally told her that I liked her, and she pushed me completely away and now says that I'm not the right person for her. It's all understandable, it still hurts but there's another thing.

A year before that this guy liked her and she turned him down, except the next week the guy died. I don't know if this is why she pushes me away I was wondering what you guys/girls think about this. Because she still says that I'm an amazing guy that any girl would be lucky to date, yet she keeps pushing me away.

What do you think?
