Fairness in relationships isn't necessarily mathematical equality.
Research on equity distinguishes between receiving identical outcomes and feeling that each person's contributions and benefits are reasonably fair.
Two partners can contribute in very different ways.
One might handle more cooking while the other manages errands; one may provide more practical support while the other contributes differently.
Problems can arise when someone consistently feels underbenefited or that the arrangement is unfair.
That means “50/50” isn't always the best description of a balanced relationship.
What matters psychologically can be whether both people believe the exchange respects their efforts and needs.
Fair doesn't always mean identical.
