Sorry I didn't mean to sound unsympathetic (sp?), but you must have known he would get in a lot of trouble or even just hassle for this, so if your thoughts were clear at the time, you must have been scared/ shocked enought to call the police.
What ever outcome you want this is going to take a lot to sort out, maybe is worried what the consequences will be with both you and his work if he admitts he was in the wrong, rather than just claiming you over reacted.
I suppose now you really have to think about what you want the outcome to be and basicly decide if you want to stay with him. If you want to stay together a big part of that might be him admitting he was in the wrong, but again if he thinks an admission may mean further action and trouble then I suppose he won't.
It really is up to you what your next move is, but I think I would want to get it square in my head, was it purely the drink, does he/ will he have violent tendencies, was it both of us just getting out of hand etc etc etc. Maybe its never going to be that clear.
Regardless of the reasons for that night, I think you will have to look at your whole relationship, and how it all works normally and under stress, how does he speak to you, how does he make you feel etc.
Maybe a wee time out needed, perhaps a day or two away at mums or friends just to give it a chance to sink in with him and time for you to get your thoughts and plans straight.
