People think breaking points are dramatic, that they arrive with shouting and slammed doors and the kind of scene others can point to later as the obvious beginning. But the truth is that many endings start in spreadsheets, bank statements, and quiet recollections no one else knows you are finally allowing yourself to put in order. The emotional explosion may happen somewhere beneath the surface, but the visible part can look almost boring. A woman at a kitchen table. A lamp on over one shoulder. A legal pad. A list.
