What does this say about him? about me? (The shortened tale of a hectic craptastic weekend)

This weekend has been hectic...
Someone who is or was my friend knocked over the hookah and three coals end up on the carpet. Needless to say the carpet totally lost that battle. It resulted in my friend/roommate getting second degree burns on her hand.
This whole time I am trying to settle down to go to sleep. My wife comes back in explaining what happened and I come out and slowly start seeing the black, burnt, fucked up spots on the floor. All the while I am pouring aloe Vera on my friend's hand and trying to wrap it.
Yes...I yell. I yell things such as "how in the fuck do you burn three holes in the carpet!"
I yell things such as "this is fucked up! This is going to cost hundreds of dollars to fix and we are trying to buy a house!"
Other things of this nature are yelled. I eventually go to bed. The friend that did knock over the hookah, the one that I don't recall saying I am sorry leaves my friend/roommate alone while she is crying in pain (my wife is in our bedroom with me thinking that our roommate is getting taken care of). He says that he is done with this shit and that I have no right to talk to him like that...
He says he's never coming back.
We have been friends for four years and this is only the second time in all those years where I have yelled at him. He has not spoken to me since.
He has not said any of this to my face.
He is one of my best friends...
I don't know or understand why he is reacting this way. If the roles had been reversed he would have probably reacted the same way. I, however, would have offered to pay. He apparently even said that he was going to pay but since I had yelled he wasn't going to. He did potentially hundreds of dollars worth of damage to the carpet and who is left to pay for it? The roommate witness who got second degree burns trying to help rectify the mess he made. And the the married couple who wasn't even in the room. How unfair is this shit? I would have said that I was sorry. I would not have ended a friendship with him.
What does all this say about our friendship? What does this say about him? About me?
I keep thinking that this will pass. I keep waiting for my phone to ding and for there to be a text from him. I keep holding back my tears because I can't accept that this is what destroyed our friendship.
I am feeling lost...angry...sad...a lot of things.
I keep asking what this says about a lot of things.

Even after all of this I have the stress of trying to get loan shit together with the house I am trying to buy.
We have a bad experience going to this new bbq place that we heard was epic.
Things are just not as good as they could have been,

My wife has tried to contact him. Has tried to tell him Happy Easter before explaining that we need to talk.
I have to see him tomorrow. He works where I work. I got him the job.
He left his work keys at our apartment. He always leaves shit here. He still has our house key.
What does all this mean? Is it really over? Can he really think that I am really overreacting and end our friendship over this shit?
Maybe we were right when we said he changed...

I guess I can only wait now...maybe some day soon he will come back...I miss him and he's only been gone two days.
