On Friday, people used the Twitter hashtag #ILeftYouBecause to unceremoniously tell their exes -- and the entire Twitterverse -- why they called it quits.
Check out the slideshow below to find out why these tweeters left the ones they loved. Be forewarned, though; clicking through could potentially present you with some serious 140-character-or-less real talk. (Hey, @M_insuperabilis' ex, apparently, "u sucked as a husband.")
Be sure to add your breakup rationale to the mix on Twitter or in the comments.
