What is the author's style in The End of the Affair by Graham Greene?

Bendrix’ point of view is ironic, self-aware to the point of pain. He tells the story of his affair with full conviction of his own suffering, and also of his own misery and his shameful behavior. This self-awareness makes the book modern in style, for it includes the narrator in the tale, almost to the point of using the tale as a technique for leading himself through a rite of passage, or ritual of acceptance, as it were.
