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.

There would be hard times, but what did I care if we had hard times? The branches of my love were wide, and they caught the rain and the snow. We would be okay, the two of us together. We would be okay.

All this to say: I am forty-three years old. I may yet live another forty. What do I do with those years? How do I fill them without Lexy?

It's not the content of our dreams that gives our second heart its dark color; it's the thoughts that go through our heads in those wakeful moments when sleep won't come. And those are the things we never tell anyone at 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.
