"I'm not going to apologize for what I did."
Sarah said it with a small, almost amused smile, as if she had just admitted to buying an expensive pair of shoes without consulting me.
We were sitting in her parents' living room on a Sunday evening, with the smell of baked apples drifting from the kitchen and her uncle talking about mortgage rates on the other side of the room. Six months remained before our wedding.

My name was still printed beside hers on a thick stack of invitations waiting to be mailed, and the woman I intended to marry had just told me she was sleeping with her boss.
I remember looking at the engagement ring on her hand, then at the matching plain band she had given me when we celebrated our engagement. I remember hearing somebody laugh in the kitchen. I remember thinking that the clocks in the house had somehow stopped, although the second hand on the mantel was still moving. Most clearly, I remember her smile, because it told me she believed she could say those words and still decide what happened next.
She was wrong about that. I did not argue with her in front of her family, and I did not give her a speech about loyalty. I went home, began canceling the wedding, and made arrangements to separate our lives as carefully as I knew how. Months later, after the man she had chosen was indicted for securities fraud, Sarah started calling me and then tried to enlist my mother to bring me back. By then, however, the most important decision I had made was no longer whether I loved her. It was whether I could ever trust her with the life I was building.
To explain how I reached that point, I have to go back five years, to a university library where I met a woman who seemed to see every possibility I had not yet learned to imagine. We were both tired, both short on money, and both convinced our lives were about to become extraordinary. I was twenty-two, finishing a computer science degree while working nights at a campus technology desk. Sarah Miller was twenty-one, studying communications and marketing, with a talent for making a room feel smaller and friendlier simply by stepping into it.
She approached me because every charging outlet near her table had stopped working. She carried a laptop covered in bright stickers and a half-finished presentation she was supposed to deliver the next morning. I checked the power strip, found a reset switch hidden behind the table, and restored her screen before she had finished explaining the problem. She looked at me with exaggerated relief and said, "You have no idea how close I was to dropping out and becoming a mysterious woman who lives near the ocean."
