If that's truly what she thinks, it's better to leave her be, my friend.
Maybe she's had some sort of experience that's caused her to become a little jaded, and her feelings may change over time. However, this does not mean she'll ever feel love for YOU, and I hope you won't be wasting your time waiting around for that to happen.
Do yourself a favour and move on. I think you know deep down that this isn't going to work out for the two of you.
Live as if you were to die tomorrow. Learn as if you were to live forever. - Mohandas Gandhi
