Girl advice much needed. Please help!?

Show up with flowers, her favourite ones, and some funny movies and a few of her favourite magazines and a deck of cards. Tell her you want to be there for her, and with her. By spending time to get to know her and being her friend you may get to be her boyfriend. There is a reason she hasn't said yes to anyone else. It maybe that she's not ready to date, or that she is scared that the guys that are asking aren't willing to get to know who she really is. When you are alone and you have had a good time together then ask if you can take her on a date when she's well again. Good luck and be brave.
