Marriage

…a gulf had opened between them over which they looked at each other with eyes that were on either side a declaration of the deception suffered. It was a strange opposition, of the like of which she had never dreamed–an opposition in which the vital principle of the one was a thing of contempt to the other. It was not her fault–she had practised no deception; she had only admired and believed. She had taken all the first steps in the purest confidence, and then she had suddenly found the infinite vista of a multiplied life to be a dark, narrow alley with a dead wall at the end. Instead of leading to the high places of happiness, from which the world would seem to lie below one, so that one could look down with a sense of exaltation and advantage, and judge and choose and pity, it led rather downward and earthward, into realms of restriction and depression where the sound of other lives, easier and freer, was heard as from above, and where it served to deepen the feeling of failure.

–Henry James, Portrait of a Lady
