What to do, what to do? Weird situation, need advice!?

Well, about a month ago, I was hanging around with this girl that I had a serious crush on. I was under the impression that she had no feelings like that for me, despite all of the signs she was showing. It turns out that I was wrong, and she did want to be with me. I was thrilled, but I don't want to go to much into that. She broke up with me four days later, for reasons that were never fully explained to me. (She said she 'Just wants to be friends') Now, about last Saturday, she calls me and tells me that she was just rejected by some guy, and that she really wants to see me. I take her to see a movie, and am just trying to be a good friend to her. She was really depressed. When I got home later that night, I realized that She was acting like she had in weeks before we were together. (A little smile she only gives to the guys she wants... poking fun at me. Laughing at even the worst of my jokes. The next day she even asked me to change my Default picture on FaceBook to a picture of me and her that she likes. She seemed a little jealous when I told her that I had kissed one of her friends in the past.) After the movie, I had to attend a friend's party. I wish I could have stuck around with her longer, but alas. At the party, I told my good friend John about this, to see if he could make head or tails of it. He said that she was talking to him about how she shouldn't have broken up with me... but this was before she realized that she liked the other guy. A couple of days later, my OTHER friend who's named John (Confusing, right?) was talking about how she was talking about me again, and that she was saying good things about me. She's still obsessed with that guy. She won't take no for an answer, and is set to ask him for the third time today. Whenever she's not thinking about him, I notice these things about the way she acts. I didn't think that I would want her back until' Saturday... I don't want to make the first move, because I might be wrong. Does anyone have any advice?
