If she invests that kind of emotion into you, it probably means there is a part of her that is still emotionally attached to you.
I would be worried if she replied to you with apathy, no feeling at all, completely indifferent. She doesn't do that, she likes to stick it to you, she likes to tell you what your place is, what you should be doing, etc. And she likes to rub your face in what she is doing, "I have a life, I'm going here, I'm doing this, I need more time for my great life, blah, blah, blah"
