Of Human Bondage by William Somerset Maugham

Hayward's visit did Philip a great deal of good. Each day his thoughts dwelt less on Mildred. He looked back upon the past with disgust. He could not understand how he had submitted to the dishonour of such a love; and when he thought of Mildred it was with angry hatred, because she had submitted him to so much humiliation. His imagination presented her to him now with her defects of person and manner exaggerated, so that he shuddered at the thought of having been connected with her.

"It just shows how damned weak I am," he said to himself. The adventure was like a blunder that one had committed at a party so horrible that one felt nothing could be done to excuse it: the only remedy was to forget. His horror at the degradation he had suffered helped him. He was like a snake casting its skin and he looked upon the old covering with nausea. He exulted in the possession of himself once more; he realised how much of the delight of the world he had lost when he was absorbed in that madness which they called love; he had had enough of it; he did not want to be in love any more if love was that. Philip told Hayward something of what he had gone through.
