If she wigs out if you don't reciprocate then she is a weirdo. Love is something that is felt individually. It's nice when you get it back when you feel it, but you should never "expect" another person - who is their own being - to feel the same feelings for you that you feel for them.
It's a wonderful thing that happens when a person can give love without expecting it back. That, in itself, is true love.
My suggestion is not to ignore her statement, but to take it as a compliment of her feelings for you, and at least acknowledge it to whatever level you can, even if you think it's something you think she wouldn't want to hear.
To ignore her feelings would be just plain rude. Her expecting you to feel the same is also rude.
