Broken Friendship: Please help!!!

I read it all (no need to post if you didn't)... and I am dreadfully sorry but I have no idea what you can do! Seems you've got a bit of a problem on your hands... well, I'm sure he cares about you still. Maybe trying to strike a friendly and safe conversation may help with things? And if he acts cold towards you then... well, the friendship may just be over.
