I wake up in that state of grief when you can tell you've been mourning even in your sleep.

I remember my wife in white.' It just made people weep to hear it...Everybody just thought it was the saddest sentence that was ever written. And it didn't matter if I never wrote another word. This one sentence had put an end to the need for any future sentences. I had said it all.

How can it be, I wondered, that we can be lying in bed next to a person we love wholly and helplessly, a person we love more than our own breath, and still ache to think of the one who caused us pain all those years ago? It's the betrayal of this second heart of ours, its flesh tied off like a fingertip twined tightly round with a single hair, blue-tinged from lack of blood. The shameful squeeze of it.

Had I known but yesterday what I know today, I’d have taken out your two grey eyes and put in eyes of clay. And had I known but yesterday you’d be no more my own, I’d have taken out your heart of flesh and put in one of stone.

Because for most of us, suicide is a moment we'll never choose. It's only for people like Lexy, who know they might choose eventually, who believe they have a choice to make.

For so long, it was just my secret. It burned inside me, and I felt like I was carrying something important, something that made me who I was and made me different from everybody else. I took it with me everywhere, and there was never a moment when I wasn't aware of it. It was like I was totally awake, like I could feel every nerve ending in my body. Sometimes my skin would almost hurt from the force of it, that's how strong it was. Like my whole body was buzzing or something. I felt almost, I don't know, noble, like a medieval knight or something, carrying this secret love around with me.

It's true, isn't it, that each of us has two hearts? The secret heart, curled behind like a fist, living gnarled and shrunken beneath the plain, open one we use every day.
