When couples marry, they often promise to stay together "for better or for worse" and "in sickness and in health." But imagine that a wife chooses a self-destructive course of action -- say, abusing drugs, profligate spending, or gambling. She refuses to listen to reason or change her behavior. Does the husband have an obligation to stay in the marriage or support her financially due to his past promise? If her self-destructive behavior causes some permanent disability, is he obliged to assist her financially or in some other way? Basically, what do the promises of marriage oblige a person to do?
