This guy really really wanted to be more than just friends with you. Like...a lot. The problem was he didn't make a move in time and it crushed him when you started seeing other guys. Some guys are just slow about that kind of stuff, and instead of seeming weak in your eyes, he pushed off the non-contact on other things like exam stress rather than admit that he liked you. He's probably brooding in his own self-pity right now, so as his friend, make an effort now to reach out to him knowing that he likes you, but be real with him and tell him what's up. He'll appreciate it in the long run.
He's probably angry and afraid that you're drifting away and beginning to value your friendships with his friends more than your friendship with him. It sucks to feel like you're losing your friend, especially when you two were as close as you say you were. You say that he got upset. Perhaps that's the reason he's being distant; he doesn't feel like you're respecting his feelings by doing something that you know clearly hurts him.If it really matters to you (and I'm sure it does), I would call him instead of waiting for him to call. It sounds silly, but taking initiative in your friendships shows that you care, and you're not just leaving all the work up to him.
He cut off ALL contact with me!!! He's my best friend.
