Whether you’ve been coupled-up for ages or updated your Facebook status to "In a relationship" just last week, every good romance can benefit from a little bond-building wisdom.

To that end, we scoured our bookshelves for the smartest, funniest, and most insightful volumes that changed our perspective on what it means to be in love—and stay in love.
