Marriage is the legally recognized union of a man and woman. After marriage, the couple becomes husband and wife.
Ambrose Bierce, the famous 19th-century American wit, defined love as being "a temporary insanity curable by marriage." Even if that is a little caustic, well over half of American weddings end in divorce, the legally recognized dissolving of the union between a man and a woman. Gay men and women have recently begun demanding the right to marry as well, resulting in the common phrase "same-sex marriage."
