Love the One You're With is a captivating novel by Emily Giffin, the bestselling author of Something Borrowed, Something Blue, and Baby Proof. This book explores the choices that define us and poses the question: How can you truly love the one you're with when you can't forget the one who got away?

Ellen and Andy's first year of marriage doesn't just seem perfect; it is perfect. Their devotion is unquestionable, and they naturally bring out the best in each other. But one fateful afternoon, Ellen runs into Leo for the first time in eight years. Leo, who brought out the worst in her. Leo, who left her heartbroken without explanation. Leo, whom she could never quite forget.

When his reappearance ignites long-dormant emotions, Ellen begins to question whether the life she's living is the one she's truly meant to live. At once heartbreaking and funny, Love the One You're With is a tale of lost loves and found fortunes that will resonate with anyone who has ever wondered "what if".
