A grown-up Interdependent Relationship (AIR) is just a recognition that is legal of relationship between a couple who aren’t hitched. This relationship need not be conjugal (intimate): it could be platonic.
To allow the partnership to be recognised as an AIR, the partnership should have specific traits. Particularly, it should be described as a relationship of interdependence, outside of wedding where two different people:
- Share one another’s everyday lives;
- Are emotionally devoted to one another; and
- Work as an financial and unit that is domestic.
