In it, my wife is sitting at a table, laughing, with her hand on a man’s forearm, and the man is leaning in toward her, and it is late, and there are drinks on the table.

That is the whole thing.

That is the entire piece of evidence on which I ended a marriage.

The man was Luca Vance.

He was a project manager at the engineering firm where Jessi worked, he was forty-six, and I had met him twice at Christmas parties and had liked him.

He was also, as I found out four years later from a man who had no reason to lie to me, gay, and had been with the same partner since 2009, and had spent that entire evening in Charlotte talking Jessi through a promotion she was frightened to take.

Her hand is on his arm because he had just told her to take the job.
