Thanks to everyone else (pretty much) for their words of support. It's a really awful situation that I can't do anything about. I'm fairly sure he knows although I haven't flat-out told him, and he doesnt seem to be any different around me; I think he just sort of accepts it.
In some ways, that's worse; I would rather like him to care somewhat, either in a good or bad way...
I know there will be comments like "Hey, at least he's still your friend" and stuff, and whilst I do appreciate that, it's kinda depressing 
Hey Hugh, take this solace-at least he is not interested in you due to personal sexual preference. It can be far worse if someone is not requiting due to looks, wealth, sense of humor, personality, status wealth et cetera et cetera. Don't be too discouraged, there is a cover for every pot.
Arroz con pollo- lay off a bit.
