Looks like he forgot how it feels like to stare a beautiful women! You are lucky I guess , from the way it sounds it looks like he is willing to do what it takes and invest in all those small things that build up a good relationship.
I personally think there is nothing wrong in being a bit ambiguous about your feelings, especially in the beginning . Don't worry about you not telling him how you feel, it is OK to hold it in for a while . Some of us are a bit more protective then others and tend to be more careful about our heart. Anyways wait until you are sure this is what you want and you are sure that his behavior/feelings are real. If he wants an answer just say you don't want to mislead him , if he really cares for you he will be patient and understanding.
