The drinking is almost a side issue with this guy. Drinking or not, he takes risks with the welfare of your family because he believes he is above the law. This is unacceptable.
Also, when I had to take alcohol classes when I got my DUI, they knew who was supposed to be there and if they didn't check in, they were reported to the PO and the Judge. Your husband may be slitting his own throat by not taking this stuff seriously. He can always be sent back to jail if he does not follow the orders of the court. It is what he deserves.
