I stumbled across The Why We Broke Up project which is based on the book Why We Broke Up by Daniel Handler AKA Lemony Snicket. According to Handler, "This website allows you to share your stories of heartbreak with us, just as we shared ours with you. Our hope is that the Why We Broke Up project will enable all of our heartbreak to reach critical mass, so that, unlike [name redacted], it will never bother us again."
As soon as I saw Handler's name attached, I knew the book and the project would be as quirky as it is awesome. The illustrations are also awesome, so you just lose. You can read the book, visit the website and share with the world why you broke up with someone... or why they broke up with you! Maybe you broke up with them because they didn't like ketchup on their mac and cheese. Maybe they were a cheating dirtbag, or maybe they were addicted to romantic comedies which you couldn't stand. Maybe they were shallow, or maybe they didn't like books! It doesn't matter, you can commiserate with Handler and Kalman, as well as complete strangers to get all out of your system and move on.
