Goodbye hug no more...?

There is this girl I have liked for a while and she might have liked me back but I never asked because I am a wimp. Anyway, we used to go out a lot. Not dating though. She would always give me a hug a the end of the night. We haven't really talked much this summer because I was working away from home and she was working on the weekends which I was home for. So I contacted her and we went out tonight and caught up yada yada. It was a short evening, just over an hour. I drive her back home and when we say our good-byes, she didn't give me a hug. It left me kinda baffled for a minute. We are going to talk online and such and go out and do something again. Am I just thinking too much into it? Or is she not interested at all?
