you know what though...if it really gets to your nerves, you can always approach him...up-front-and-personal...and demand what is going on between you two. It sounds awful and disgraceful, but I can say from experience that as a worse-case scenario, I feel it relieves you of the pressure of "does he/he not like me" feeling and just letting you move on. It happened to me once...and if i did not say it to a past crush and she denied me, I wouldn't be dating the wonderful girlfriend I have today.

otherwise...patience is a virtue; just let it flow. I feel even if this fails...we'll still be here for you.
