Classic reconciliation usually goes something like this. Underneath it all, the two still love each other. It's just that all the crap they've been going through has obscured this, and their petty fights compound what are somewhat stubborn personalities. However, a crisis brings them together again and opens their eyes to their true feelings.

Die Hard is the perfect example. As the movie begins, we learn all the conflicts that have hurt their marriage. Note how they snap at each other. We also know, though, that they'd really like to work something out, because Holly invites McLean to stay in the "spare bedroom" of her house.

By the end of the movie, with all the mayhem, etc., they understand how petty their disputes have been. McLean saving Holly from the terrorists is the fulcrum to opening both their eyes. Saving one partner - or both partners saving each other - from a crisis is a frequent way to go.

Good luck!
