Couples often won't change unless they're in a crisis because comfort breeds inertia. A counterintuitive therapeutic technique is to intentionally apply pressure to "put them in crisis," forcing the couple out of their comfort zone to confront issues and make necessary changes.

A breakup isn't just the loss of a person; it's the death of a unique 'microculture' built for two.
