How do I fix this mistake and win her back?

e we're really close once. We havent talked for a yr due to a fight, but met a month ago for coffee. She won't respond to my texts anymore. She said we could be the best ever once.. I sent her some long text making me look weak. Why can't she say it's done instead of ignoring me? How do I handle this? Is she playing hard to get? I feel like a needy ***** when she doesn't respond . The **** do I do? I just want be her friend again. It's not over til she says it's over... ignoring my texts doesn't count as ending it! I will annoy the **** out of her til she says it's over, that how far I am willing to go for this girl! She means a lot to me and I want to fix my mistake. How do I get her to remember how genius and special our friendship was. In all honesty, we were the closest
