I sat down. I don’t even remember pulling the chair out, I just remember being in it. I asked her to repeat the part about the pancakes, which is a stupid thing to fixate on, but in fifteen years Mark never once made me a pancake.

Not one. He says batter is a waste of time. And meanwhile some woman two blocks from my hairdresser is flipping them every Saturday for a baby named Maya. The pancakes are what got me. Not the door. The pancakes.

“There’s more,” Debra said. And I almost told her to stop. I almost hung up. I think part of me already knew that whatever came next I wasn’t going to be able to un-hear it. But I didn’t hang up.

“She said the other mommy told her to keep it secret,” Debra said. “She told Lily it was a special game. A grownup game.”

A game. They turned my four-year-old into a little secret-keeper and called it a game. She’s four. She doesn’t even know what a secret really is. She just knew Mommy wasn’t supposed to know about the pancakes.

I drove past that house an hour later. I told myself I wasn’t going to, and then I had Lily in the car seat with her snack cup and I just went. White siding. Blue door. The little plastic slide, faded yellow, tipped on its side in the yard like nobody had played on it that morning. And in the driveway, next to a car I’d never seen, was the gray hoodie I bought Mark two Christmases ago. Hanging on a hook on the porch like it lived there. Because it did.

Lily saw the house and got excited. “That’s the other house!” she said, like it was Disney. “Can we go see Maya?”

I didn’t take her in. I want credit for that, even though I don’t deserve much.

I sat at the curb with my hands shaking and asked her, real calm, like it was nothing, “Baby, who’s at the other house?”

And she listed them off like a grocery list. “The other mommy. And Maya. She’s a baby. And Daddy on Saturdays.” Then she looked at me in the mirror, a little confused, like she felt something was off but couldn’t name it. “You don’t come. You’re the home mommy.”

The home mommy.

I called Mark from that curb. He answered all normal, “Hey, what’s up,” and I said, “I’m parked outside the blue house.” Long silence. Then, real quiet, “Where’s Lily.” Not “let me explain.” Not “it’s not what you think.” His first words were where’s Lily. That told me everything about what he’d been planning. That told me who he’d already decided got to keep her.
