But it was her.

For six years I had buried the memory of her under grand openings and investor dinners and red-eye flights, and my mother had handed me, over and over, an explanation gentle enough to swallow: that Sabine had realized she did not belong in our world, and had chosen to walk away with her dignity intact.

I had wanted to believe it, because the only alternative I could imagine — that the woman I loved had simply left me — was too much to carry.

It never once occurred to me that there might be a third possibility, worse than either, sleeping now against a wall in Terminal 3 with two children beside her.
