Portrait of a Marriage, by Sandor Marai

This novel is an account of the formation and demise of a marriage told from three points of view: the wife's, the husband's, and the husband's mistress's. The writing and situations were realistic and convincing enough, but there was too much focus on class differences in the book: the husband could be described as upper middle class, the wife lower middle, the mistress (who was the housekeeper in the husband's mother's home), is working class. Since they all knew each other's background before choosing to get involved with each other, I did find it tiresome that they kept on feeling so self-conscious about it, even after getting married. If class differences are that important, why not marry someone else? And I didn't find any of the three main characters likable, so I didn't enjoy the book as much as I could have.
