The whole Scene:
Rationality did not appear to be helping much. I turned to emotion, and began, shrinking from the task, to reconstruct the details of my married lives—first with Frank, then with Jamie. The only result of this was to leave me shattered and weeping, the tears forming icy trails on my face.
Well, if not reason nor emotion, what of duty? I had given Frank a wedding vow, and had meant it with all my heart. I had given Jamie the same, meaning to betray it as soon as possible. And which of them would I betray now? I continued to sit, as the sun sank lower in the sky and the swallows disappeared to their nests.
