And sometimes when you're in a bad situation, it's not because of any _one_ thing, or even a myriad of things ~ sometimes it's because it's the whole kit and caboodle. When I was younger, I found myself on the side of a breakup asking "What did I do? Tell me and I'll fix it", and I've also been asked that by someone I was breaking up with.

Breaking up is hard, for both sides. Sometimes it can be something singular (e.g. an affair) that can make it easy to digest, but sometimes it's so vague, it's such an overwhelming collection of things that span such a great amount of time, that even trying to enumerate them is a slide backwards. It's like death by a thousand pinpricks, but there's no clear indication that things are dead until you're already waaayyy past the point - like a frog being slowly boiled.
