there is no real easy answer. Without knowing her myself, giving advice is tricky as everyone should be treated as the individual they are.
If, after the three days, she wants you to be part of her life, nice one. If the amswer is a flat 'no', then i'm afraid you really should move on (I know thats not what you want to hear, but you will make it worse if you persist.
If, on the other hand, she is uncertain, then give her breathing space. Definatly let her know that you're there for her, but do not push too hard (see above).
Emotions are tricky, and, as i've said, each person is different. Hope this helps
