<human>: Give me the gist of the text in a nutshell

I'm not too comfortable sharing our ages, but there is a four year difference between myself and the girl in this post. The girl is a very cheerful, easy-going gal. She's very friendly and is almost always smiling.

So, I had this crush on this girl, but she didn't like me back. She just wanted to stay as friends. At the moment, I thought that I wouldn't want that, and that it was best to end our friendship. So after a lot of pondering, I finally went through with it and I told her that our friendship was over. I told her this in person, mind you. After I told her, she stayed a few moments before saying, "I'm sorry, I can't," and walks off. I probably should have followed her, but at the time, I thought it was best for her to go. 

Later that same day, I tried talking to her today, and I told her what follows: "I'm sorry, it was unfair for me to say what I did, but it is also unfair for us to do what you ask (which was to stay as friends). So, what are we going to do?" She ponders a bit and replies with "I think we'll do what you wanted (to end our friendship)" and she walks off. Even me telling her was stupid, for nothing was unfair, I was just being selfish...

I want to rekindle our friendship. Apologizing to her will be the easy part, the difficult part, I believe, will be to get a moment of her time to explain everything and apologize. I'm thinking the next time I try to talk to her, she'll just walk off or ignore me completely.

How do I get her to talk to me long enough for me to apologize? How can I rekindle our friendship? I'm willing to do anything to set things right..
<bot>: Lost a friend, want to get her back. How do I rekindle our friendship when she won't listen to a word I have to say.
