i can totally see how the attraction can develop. you're with this friend a lot, know the ins and outs of him. if you 2 were both attracted to each other its jsut like being attracted with any other joe schmo. throw it out there if your interested in him, if you're really good friends, he won't be weirded out or anything or if you feel he's attracted to you as more than friends, approach him. if you both don't wannna go "there" then just leave as is.

if you 2 were meant to be more than friends it'll happen, when the time is right....w/o a dealine.
