Tell him right away its better to find out now then to weight a while
i personally think that either he doesnt really know you or he is trying to hide the fact that he does know you and has a crush on you but doesnt want to admit it.

Tell him you like him and probably doesn't know how to ask you out.

Ask him!
sasuke doesnt have mercy for any1 nor does he love any1 since his family died when he was very young. he doesnt loove anybody and doesnt get married ...that we know of
He could have gotten over his crush, is trying to get over his crush and does not want to ask you out, or does like you but does not know how to show it.
asking him would work
get to know him then he won't be shy
