I did it on my lunch break, and I said nothing, and I watched.

Because I had learned, by then, something it takes some women a long time to learn: that when a person shows you what they are willing to do, the wise response is not to argue with them about it.

It is to believe them, and to prepare.

I had spent most of my marriage doing the opposite of that, and I want to be honest about it, because I think it is the most common mistake good people make and the one that costs them the most.

For fourteen years, whenever Jason or his family showed me some small, ugly truth about how they saw me, my instinct was not to believe it but to explain it away — to find the generous reading, to decide I had misunderstood, to give the benefit of a doubt I would never have extended to a stranger who treated me half as badly.

When Jason let his mother call me controlling and said nothing, I told myself he was keeping the peace, not that he agreed.
