Always?

Nancy and Tom were the epitome of unexpected. How often do people meet at a completely random dance class in the middle of January on a Saturday afternoon? Truth is, they had something no one else could claim. Sort of a "relationship copyright" or trademark. They came from pitch-black pasts of depression, sadness, and crippling insecurity. After that one night: it all changed. They made a group of friends "The Misfits", because let's face it they are outcasts of the hooking-up, make-out-in-the-middle-of-the-street society they live in. They spent hours having discussions and making awkward jokes at serious times and struggling to keep in laughter. They would be together always. Or so they thought: Tom has massive family issues and they are in the process of divorce. One argument drew the line for Nancy.
She couldn't take it anymore. Will they keep their quote of "always" true? Or do away with it?
