Think of what you accomplished by not drinking last night: You responded to his behavior with a clear head and a relatively calm demeanor (something that always escaped me when I was drinking). You showed your kids that at least one parent is stable and deserving of respect. You cooked what sounds like an awesome supper. And you woke up this morning not having to worry about you and your own behavior was part of the problem last night.
So, you DID show him. In a good way.
