When a relationship suddenly ends, at least one person is usually left deeply confused, and possibly more, depending on how many chicks you're banging when your girlfriend walks in. For helpful insight as to why you can't date a chick long enough to make that a realistic scenario, there's WotWentWrong.
Straight outta Melbourne, WWW allows the recently abandoned an opportunity to discover exactly why their calls stopped being returned, incentivizing the heartless half of the equation by offering a chance to see how the fool they left behind rates them in a handful of personal categories (hint: highly enough to care they got dumped).
After specifying how long they were in said relationship, users can craft a nifty four-paragraph email request using editable boilerplate copy with tones like "Confused", "Flippant", and "Historical", which is for long-ago relationships, and not that chick whose muzzle you totally loaded at last year's Civil War Reenactment.
Next, rate your extinguished flame using a 1-to-5 scale on a handful of fronts (kissing technique, fashion sense...), and optionally throw in your own question (if you're stuck, they recommend "What did you think about the sex with them?", because there's nothing a woman wants to be reminded of more than sex with a man they desperately try to avoid).
Should your email convince them it's worthwhile to barrage you with all your crippling deficiencies, they need only link through to peruse a dozen main categories (You're Too Much, Lifestyle, Physical/Sexual) loaded with click-to-add issues ranging from "Not generous enough", to "You aren't over your ex", though technically she wasn't one until she walked in the room.
