Does he know?

Does he know that dreams about him still interrupt my sleep? Does he know that he changed me and I can't change back? Does he know that I don't go one day without thinking about him? Does he know that he has hurt me more times than I've told him? Does he know that I know he's making a huge mistake? Does he know that I know that he is just ignoring and avoiding me? Does he know that I can never forgive him? Does he know that I will never ever forget him? Does he know that I know? Does he know how much I gave up for him? Does he get it? Will he ever know? Will he ever understand?
