A: There are lots of reasons people in committed relationships don't get married. Some women don't want to be wives, and would rather be partners. Some have had horrible experiences with divorce and don't want to risk that again. Some people would lose significant financial benefits if they married, like senior citizens who can lose a pension from a deceased spouse. Commitment and marriage often go together, but not always. Of course, there are married couples who aren't very committed, and whose unions don't last long. And there are also unmarried partners whose relationships last many decades, who are as committed as the most loving married pair. We need to learn to understand marriage and commitment as existing separately from each other, sometimes going together, sometimes not.
