Several times over the years, married friends of theirs split up because one partner cheated. Each time, the husband and wife shook their heads.
I don’t understand how it gets to that point, why people don’t try to work things out, she said.
I don’t either, he said.
Promise me that if you’re ever thinking about cheating you’ll tell me before you do it.
I won’t cheat.
Just promise.
Okay. I’ll tell you.
The husband keeps this promise.
