There was one final letter after the mediation, shorter than the first and far more honest in tone, if not in total understanding. He wrote that he knew he had ruined everything but could not figure out when, exactly, the point of no return had arrived. I read that line twice because it summarized him better than anything else he had ever written. Men like Ethan rarely recognize the real ending when it happens. They imagine the end is the confrontation, the signed papers, the day the boxes appear on the porch. In truth, the end had happened long before that—in the moment he booked the ticket, or maybe in the moment he believed my trust was durable enough to exploit. I did not answer the letter.
