The Reinforcing Trap

The relationship between an overfunctioner and an underfunctioner translates into dangerously reinforcing each other's habits: The overfunctioner takes on more than their fair share of responsibility from housework to finances while only reinforcing the underfunctioner's dependency.

A relationship like this often curdles that could to lead to fighting or nagging. This applies not only to romantic relationships but it could also be happening at work and between family members.
