Be honest with her, and talk to her in a way so that she knows you care about her... Its not easy to have to deal with this, but patience and perseverance help, dont give up on her. She needs you, whether or not she knows it. Talk to her, and tell her that you love and care about her, and ask her to do it for you, and that you will be with her every step of the way. She needs someone to understand how she feels. Be gentle and understanding.
