Love has, quite unfairly, come to be associated with being happy. However, it is also one of the most reliable routes to misery. We tend to treat our sadness individually, as if it were unique and shameful. But, as this book explains, there are some solid reasons why love should be highly sorrowful at times. The good news is that, by understanding our romantic troubles and griefs, seeing them in their proper context and appreciating their prevalence, we will cease to feel so alone and so cursed. This essay is not a study in despair; it is a guide to a more consoling, humane, and in its own way, joyful perspective on the complexities of love.
