From Anna Karenina
For some time, I have known that in uniting my life to yours, I have made a mistake. But this I must bear for the sake of my public duty... and for the sake of my child. I believe in marriage as a sacrament. I could not consider myself justified in breaking the ties by which we are bound by a higher power. The family cannot be broken up by a... whim or a caprice or even by the... by the sin of one of the partners in the marriage. Our life must go on as it has done in the past.
But it can't go on.
