Everyone should ask a more specific question: What do I want most out of my life? If a person wants peaceful life, he or she should get married. If a person wants freedom, he or she should remain single. Can a person have both a peaceful life and freedom? There is such a thing called an open marriage. But marriage is on the threshold of freedom. In reality, perhaps it is easy or difficult to cross that threshold. But the threshold must be there. Without it, the marriage would be totally open, and the union could not be regarded as a marriage. It is essential that in marriage the idea that the展开更多
