What does it mean when a guy rubs your back?

Anonymous
Me and this guy have a complicated relationship. Sometimes we are friends and sometimes we ignore each other. Its been like this for a year now. We get along and we don't get along. But we have never been really close friends. People always say there is this tension between us when ever we are around each other. So anyways, we haven't been talking to each other for a while now even though we see ach other almost every day, we just ignore each other. We are not fighting or anything like that, no bad vibes at all. So the other day we were at a theatre and I was sitting with my friend and he came to sit with us but next to my friend not me and we were all laughing the entire time and at the end of the night as we were leaving, he was walking behind me and he rubbed my upper back. I know its not a big deal but still I want to know why a guy who hardly talks to you would do this.
