She knows deep inside she wants to risk being vulnerable and give in to what her heart is telling her to do.
Learning how to get back out there is insanely difficult, almost impossible. Understand that picking up the broken pieces has become a habit of hers; that she will never get used to giving everything she has and gaining absolutely nothing from it.
She needs constant assurance. Nobody wants to hang on to false hope.
Please give her time. Work on yourself before getting into a relationship because you simple cannot give what you do not have. Many people know how to feel, but have no idea how to love. People often get confused by this which is why they get hurt easily.
