My AH has never been violent before and I don't think he will be now. He has a bad temper and at worst he slams his hand down on the table or thumps a wall but that is about it.
The only thing I would say is that I am a tiny bit scared of him when I don't know how he is going to react to something. If he gets angry he doesn't shout he just simmers, glares and starts lecturing/questioning me. But then when I am angry I yell a lot so I am no saint!
Maybe I have made him sound worse than he really is.
