Why does he avoid touching me?

My coworker was really touchy-feely 3 months ago. He didn't hesitate showing affection in public... he hugged me, made shoulders massage, etc.

Out of the sudden he started avoiding doing that. I get the feeling that he wants to do it, but something is stopping him.

Yesterday we talked a bit near my car and he grabbed my hand 3 times in 15 minutes. But he is avoiding doing it in the office (almost at all costs).

I thing the manager has something to do with that. Do u think so?
