Has he actually said or done anything specific that leads you to believe his feelings for you are less than professional? You gut feeling isn't really a good indication as this all gets wrapped up in transference, etc., and you do seem to be rather overly obsessed with him. Unless I've missed it, you haven't ever mentioned anything specific he has done. Him just saying he cares for you, telling you that you are an attractive person, and that you are intelligent don't really reek of an attraction to you other than professionally; those could just be pretty standard compliments depending on context.
