she is definetly ana, i am 5'0 80 pounds, my bmi (basal metabolism weight) is underweight and she sounds alot thinner than i am. I have a friend who is anorexic and her boyfriend, to get her to stop, gave up eating and then my friend was really upset and tried to make him eat again and he said the only way he would was if she did. it sounds drastic but it might help her realize how much she is hurting you. If nothing else works give it a try.
