Well us guys are stubborn asses! I don't know why but we have a real problem expressing our feelings (we'd rather act all pissy and go off somewhere to be all dark and brooding by ourselves
) but we usually smarten up when our girlfriends give us a mental slap upside the head. Talk to him seriously about it; he'll come around if he feels as strongly for you as you do for him. And I know he does; just from reading your post I can tell you guys could be "in for the long run" if you get my meaning!
