Valentine’s day may be the perfect opportunity to get engaged. It’s also the perfect opportunity to rethink, reshape, and redefine the meaning of marriage for the 21st century.

In The New I Do: Reshaping Marriage for Skeptics, Realists, and Rebels, therapist Susan Pease Gadoua and journalist Vicki Larson examine the institution of marriage and outline alternative models for matrimony, including a “parenting marriage,” a “comfort” or “safety marriage,” a “living alone together marriage,” in which partners live in separate homes, and more. In the book, Gadoua and Larson explore the pros and cons of each model, while providing real-life examples and pointing to additional resources for interested couples.
