Regardless of the circumstances in which she grew up, she has been taught to believe in romantic love and the essential perfection of married life. Failure is personal. Individuals fail because of what is wrong with them. The troubles of individuals, pervasive as they are, do not reflect on the institution of marriage, nor do they negate her belief in the happy ending, promised everywhere as the final result of male-female conflict. Marriage is intrinsically good.
Marriage is a woman's proper goal.
Wife-beating is not on a woman's map of the world when she marries. It is, quite literally, beyond her imagination. Because she does not believe that it could have happened, that he could have done that to her , she cannot believe that it will happen again. He is her husband . No, it did not happen.
