You could, very casually, ask him out, say to the movies or something. By spending time alone with him, you will be able to assess the situation better. As well, you'll be in a position to initiate conversation, first of a general nature, and then as time passes, of a more personal and initimate nature. The fact that you are friends is great; you have a history together and can talk about interests and events you have shared already.


Be yourself. He may be feeling exactly the same way you are today.


All the best.
