Edith Wharton,
The Valley of Decision — Book IV, Chapter 6
(1901)
“ Better, perhaps, than Fulvia, he knew what ailed them both. Happiness had come to them, but it had come too late; it had come tinged with disloyalty to their early ideals; it had come when delay and disillusionment had imperceptibly weakened the springs of passion. For it is the saddest thing about sorrow that it deadens the capacity for happiness; and to Fulvia and Odo the joy they had renounced had returned with an exile's alien face. ”
