What do I do about my friend not talking to me.?

This Valentine's Day will mark exactly one month since my friend stopped talking to me.

Basically I have strong feelings for this girl and I let my feelings cloud my judgment and I started acting weird towards her. I ended up making her uncomfortable. Basically she said I was being a creep. I realized what I had been doing before she even said anything and apologized, but it was too late. The last thing she said to me was "Give me some time, maybe we can start over"

Well it's been almost a month now and I am starting to get worried that this may be permanent. I have apologized to her many times and I really do feel horrible for what I did, but I can't get anything out of her. She won't even say hi to me. I really miss her and want her to like me again, but I don't know what to do anymore. I've tried everything I could think of (except for threatening or lying to her. I am not trying to force her to do anything) but I just can't get her to budge. This really has me down. I can't stop thinking about her. Everything reminds me of her. I so badly want things to be good again so I can try to handle things the right way. I really want to change.

There are some positive signs. She hasn't blocked/removed me on any of the things that I have contact with her. (Myspace, Twitter, Cellphone, Xbox live, skype)

I just don't know what to do.
