This gives you completion as well as practice in renewal. This helps you finish incomplete situations from the past so you can begin living in the present, being present to each other, and living toward the future. This opens up the possibility of working together, in communication with each other, in agreement about what you are both dedicated to accomplishing.

An honest relationship with other couples supports your couple. Couples need another couple or two for friends. If intimacy doesn't extend to friends and extended family, the network of support is too thin.
