This book is a fearless, authentic look at long-term relationships and what they entail, from the ridiculous fights couples have to the awesomely cheesy proclamations they make and the micro-milestones they reach along the way. When you commit to building your life with another person, there are countless ups and down and awkward moments in between. You're not really a couple unless you're primed to enjoy—or at least survive—the entire ride.
