For her new book, sociologist Danielle J. Lindemann, interviewed nearly one hundred commuter spouses—couples who live apart in service to their dual careers—to find out what this unique group might reveal about broader trends in marriage. In Commuter Spouses: New Families in a Changing World – featured today on BBC Capital—Lindemann details what they told her about their unconventional marriages and finds that commuter couples have a lot to teach us about the changing dynamics of gender, family and work in the U.S. Ultimately, she argues, commuter spouses illustrate the “stickiness” of traditional marriage ideals while simultaneously subverting expectations.
