Karl, all you really need to do is keep repeating these three things:
1. I'm Sorry
2. Yes Dear
3. I'll never do that again
That should get you through the first 20 years or so...
My wife and I would have gotten a divorce years ago, but neither of us wanted the kids.
As one Capt. told me many years ago, "Do you know why a Divorce costs so much money? Because it's worth it!"
