“You must be Sabine. I’m Delphine. I’m leaving. The party is yours.” I picked up my coat, walked past her, and shut the door. Thirty guests were inside, his ex was standing at the entrance, and my duffel bag was already in the van. The entire decision took eleven seconds. I had texted my friend Margot from the bathroom earlier, and she was waiting nearby. We drove to her apartment, where she poured us wine. Neither of us talked much. Sometimes a good friend knows that silence is better than advice.

Later, I learned what happened after I left. He stood at the open door, staring at his guests as if everything he had planned had suddenly fallen apart. Sabine never went inside. Instead, she looked at him and said, “I told you this was a bad idea.” She had warned him before coming, telling him that inviting his ex was unkind. He assured her that I was mature enough to handle it, so she trusted him and came. In the end, she trusted her own judgment more.

He called eleven times that night. I answered none of them. His messages changed from confusion to defensiveness and eventually to something closer to remorse. I stayed with Margot for two weeks while I decided what I wanted to do. During that time, the answer became clear. Whatever had happened at that party was not something I could simply forget or excuse.

We divorced. The apartment was his lease, while the van and tools were mine. My grandmother’s jewelry stayed with me, and there was nothing left to divide except the truth. I continued living in Brooklyn and kept working as a plumber. The wrench I had dropped on the kitchen floor that night now sits on my workbench, and sometimes I remember the sound it made when it hit the floor.

He later asked through a mutual friend whether I had planned everything from the beginning. My answer was simple: “I only planned to be exactly as mature as you asked me to be.” It was the truth, and by then, it was all that needed to be said.
