You can:
1) Keep trying (i.e. telling her how you feel and hopefully she feels the same way). This route is definitely not recommended, because you will risk pushing her even farther away;
2) Focus on healing. No contact is a helpful tool, because it helps prevent you from building false hope and over-analyzing all the details;
3) Stay friends in hopes of something more.
Warning
You've choosen, 3) the "limbo" route. You're not trying to win her back, you're just putting your life on hold by sticking around and hoping that she will come around. This will:
a) prolong your pain and suffering
b) set yourself up for a huge disappointment
c) prevent you from fully healing
I vote for option 2)
*Once you've fully recovered, you will be in a better position (calmer, emotional dust setled, more objective) to re-visit your situation
