About 5 years ago, DH lost his driving license for drink driving, and I said to him that if he ever drove drunk again I would split up with him. He has been impeccably behaved since then.
Tonight he had 3.5 pints of average strength lager and then we ordered a takeaway. He went down to get it while I looked after the baby. I thought he had walked down but it turns out he drove. Half a mile round trip on a very quiet road - it's unlikely he'd pass another car at this time of the evening. He thought that because it was so close and he didn't feel drunk, and the weather was so awful, it would be okay.
He's staying here tonight as he obviously can't drive to a friend's, and he has to leave for work at 6am. I've told him that from tomorrow he can find somewhere else to stay.
I feel sick to my stomach. Aside from this, he's a wonderful husband and father.
What the hell should I do?
