Interdependence

On the maturity continuum, dependence is the paradigm of you — you take care of me; you come through for me; you didn’t come through; I blame you for the results.

Independence is the paradigm of I — I can do it; I am responsible; I am self-reliant; I can choose.

Interdependence is the paradigm of we — we can do it; we can cooperate; we can combine our talents and abilities and create something greater together.

Dependent people need other’s to get what they want. Independent people can get what they want through their own effort. Interdependent people combine their own efforts with the efforts of others to achieve their greatest success. 

— Franklin Covey, The 7 Habits

It's important to note you can only get to a healthy interdependence if you've developed good boundaries and independence. Trying to jump ahead to interdependence before you've developed these leads to co-dependance, which we don't want at all.
