hmm.. I think its a pity you decided to start all this when you were 'drunk' (not sure how drunk you mean, you seem to remember everything..

)
... how about you two sit down in some quiet place and you just talk to him...??
.. you could tell him that you feel attracted to him (just to clear it up and so you 'own' your feelings and he can no longer lord it over your head).. then tell him you would like to know what he thinks and how he feels.... you can use the 'I like you as a friend, but there could be more here, if we are both interested' approach'... that way you can tell where his head is....
... if all he wants is an ego-boost then you can walk away with just a little embarrassment, but you can also learn more about how he feels about you... especially if he is not interested... I'm sure you will be able to pick up on it....
or... you can keep playing the guessing game based on clues that you are not sure of the meaning of....
