Should I tell my good friend that I've become attracted to him?

One year ago I started an intensive MFA program. I was given studio space with a man with whom I sensed an immediate attraction. Even though he gave initial signals, I chose not to pursue them for a number of reasons. First, I was weary of getting involved with someone when we were in such close forced proximity, especially when I didn't really know him yet. (I had been involved with a co-worker before and when the relationship ended, working with him became very uncomfortable.) I was seeing my studio mate many hours a day at least six days a week. Also, at the beginning, I wasn't so sure about his personality and he seemed to come on too strong too quickly. But as the months ped, I grew to like this man very much as some of his initial questionable personality traits turned out to be a cover to his real personality beneath. On my side, the ual tension never ebbed, but even grew as I got to know him more. The problem is that now we are in friend territory and have at least one more year in these close quarters, although from now on a little less close as we pursue our art into different directions. I fear that because I did not allow him to make a move in the beginning, that he does not see me as a potential mate anymore. I don't want to ruin our friendship and I don't want to make our shared time in studio together uncomfortable, but really desire to pursue a romantic relationship with him. I used to think the attraction would fade with time and I could turn my attention elsewhere, but it hasn't. I've never felt a connection this strong that has lasted this long. Should I confront him?
