Can you and the children go somewhere today?
I know what it feels like to sit at home with an alcoholic that just got into trouble with the law. The alcoholic will want someone, especially you, to make them feel like it is all going to be okay.
It is not okay.
His alcoholism = His consequences.
Have you started attending alanon meetings yet? If so, can you call a member from your group? They will be able to help you talk through this crisis.
If not, you can share and vent here as much as needed.
