By now you’ll have gathered that for months I’d tried my hardest to remain blind to what was between you and Tom. But after Julia’s naming of his disposition, my husband’s relationship with you began to come into sharp, terrifying focus. Comme ça: the words themselves were dreadful—they conjured an offhand knowingness that utterly excluded me. And I was so stunned by the truth that I could do nothing but stumble through the days as normally as possible, trying not to look too closely at the vision of the two of you that was always there, no matter how much I wished I could turn my eyes away.
