Girl's Behavior

If a girl says bye first?

So my crush at church just moved, and she said bye to everyone that said bye to her the last time we saw them. Mostly her friends and the other people that said bye to her she said bye and all that. But with me she first said "Bye" and then my name to me. Like she was walking to her car and I was in her direction, and there were several people around me. I was about to talk to one guy and she looked at me and said bye to me as she walked by. We don't really talk talk, even though we've had some good moments, but it's complicated since there have been very mixed signals. And I was the only guy she said bye to, and the only one who she came up to and said bye first. So is this a good sign?
