Yes, talk to him and tell him exactly what your T says (if you feel this way of course). But don't expect to find out much. It would surprise me if you did. It seems that he is working his way in quietly so that he doesn't have to make any committments like "I am here to stay, ILY SOOOOO much, etc" . In some cases there is a delay between doing and saying, maybe he is one of those...
