He tried the old lines—let’s talk, we can fix this, she’s not my legal wife—but by then the words were hollow. I told him to go to his other family. Before he left, he said he was sorry.

“So am I,” I said.

“Why?”

“Because I wasted so much love on such a small man.”

That night I called my daughter Emily. I told her and my son Ryan to come the next day. I couldn’t say everything over the phone yet, but I needed them beside me. At dawn I changed the locks. Then I called my friend Susan from book club, who also happened to be a divorce lawyer.

“I need a divorce,” I told her.

“Come this afternoon,” she said, calm and serious.

At her office I told her the whole story. She listened, then closed her notebook and said, “It’s a clean case. Ugly, painful, but clean. You have rights, and we’re going to protect them.” It was the first thing that sounded like structure. Pain spills everywhere. The law, at least, has edges.

That night Emily and Ryan came over. I told them the truth. Their father had another family. Emily cried quietly. Ryan paced the room like he might explode.

“I’m going to kill him,” he said.

“No,” I said. “What he did is punishment enough.”
