Why We Love

What it is about

Why We Love is Helen Fisher’s account of romantic love as a motivational system, written for a general reader from the brain research of its time. She separates three systems that couples often collapse into one feeling: lust, romantic love, and attachment, which can be present together or pull in different directions. The book is useful when a pair is trying to tell early obsession, sexual wanting, and the calmer bond of attachment apart, including the craving that can follow rejection. It is science writing, not a marriage-repair protocol, and not a claim that a scan should choose a spouse.

Questions it can answer

• How does Fisher separate lust, romantic love, and attachment?
• Why can early obsession feel like a drive rather than like a decision?
• What does the book help a couple notice when those three systems do not point the same way?

What you will not find

• A protocol for repairing a marriage or healing an affair
• Proof that a brain image should decide whether to marry
• A settled claim that the chemistry described in this book is the last word
