I agree it would only be guessing. If you were to look at anything he said as a clue, however, the fiancee was mentioned when he might have been feeling as if things were getting closer. Perhaps it was because he was trying to say something about it. He may feel it is too soon or is hesitant to get involved. Being around him in a non pressure setting with no expectations would allow him to get to know you and decide if he wanted to get more involved. I think you are right in letting him make the next move. Just continue to be yourself. He obviously enjoys your company. All good relationships begin as good friendships.
