From reading your post, IMO your communications skills and your heart are both working well and true, but this girl's are not.

Unless she is willing to, with all of her heart, say that she understands what you said and why, I would agree it's time to go.

There is no reason why you can't go on loving her, but from what I read, every reason why you can't go on being with her. Say your peace to her, from your heart, and move on.
