I'm going to get downvoted straight to hell here but that'll be the price.

You talk him up in several ways and say nothing but positive things about the man. Yet when he is angry your first response is to barricade yourself in a room in the house? I don't understand the logic. Even your story says the table was big and heavy. If he is such a nice guy and has just flown off the handle what makes physical barricades seem like something that will calm him down.

I think you may have been a little more tipsy then you think. I don't follow the train of thought that led you too blockading your kitchen from your fiance who is "sort of person you can count on to do the right thing"

He is completely in the wrong for how he acted but I do believe that you escalated the situation to a different place with the blocking yourself in a room maneuver. Have you talked with him about this? when he said it was partly your fault was this the kind of thing he was trying to say?

Anger issues are a real and serious problem and until someone learns how to control them it can be really tough. It could also be the booze, sure it's a problem but sometimes people have bad nights and get to fucked up mental places since they are intoxicated. Every response here I read is trying to turn this into a pattern when really there's only one point of data.

Is he usually bad drunk? Does he typically drink? If he doesn't drink a lot is there a reason for that ?

If anything of this sort has happened before or if there are issues in the past that mirror this then yes GTFO. But otherwise it may be possible to chalk it up to a bad night of drinking.

TL;DR anger issues and too much booze don't mix but don't make someone a wife beater.
