I work with a guy, we are friends, i am fairly sure we are attracted to each other. Eye contact /nervousness etc. But, i really do not know! I was talking to him to him recently and in general conversation , i bit my lower lip ( something i genuinely do when i am nervous- have done all my life) and /or I fancy someone , without realising i am doing it. I genuinely genuinely did not do this on purpose, it was involuntary. He immediately clocked it and then instantaneously turned his head away to the left for about 2-3 seconds, then he turned his head back to look at me. He looked a bit shell shocked to be honest. I have been wondering what his very immediate /reaction momentary head turn away means? It was just such an immediate reaction. I am worried i have offended him in some way. I have seen him since this and all fine. I just need to understand what that reaction was all about.
