Do you think he likes me?

I have a bunch of guy friends and none of my guy friends are friends with one another. One of them I have known for four years but never really like-liked. the other day we were working on homework together, and now i have like a huge crush on him. he really cares about me and considers me his best friend. he is one of the only friends i have that cared when my gma (i lived with her) died and came to the funeral. he always gets happy when i say i am going to one of us sporting events and cares more about my life than his own sometimes it seems.
