She was breathing heavily, not looking at him. She was feeling
ecstasy. Her soul was flooded with happiness. She had never
anticipated that the utterance of love would produce such a
powerful effect on her. But it lasted only an instant. She
remembered Vronsky. She lifted her clear, truthful eyes, and
seeing his desperate face, she answered hastily:
"That cannot be...forgive me."
A moment ago, and how close she had been to him, of what
importance in his life! And how aloof and remote from him she
had become now!
"It was bound to be so," he said, not looking at her.
He bowed, and was meaning to retreat.
