Interdependence

When forming deep, intimate relationships, we share a vast amount of personal information that we wouldn't necessarily feel comfortable sharing with others. 

We feel safe sharing our deepest dreams, desires, fears, past histories, traumas, and goals for the future. Generally, this is a reciprocal and gradual process.

While the display of care can differ from one person to the next (as a function of communication style or differing displays of affection, for instance), intimate partners tend to display genuine, selfless care for each other.

Trust is the confidence that we place in another human being to act in a way of honor and fairness that is of benefit to us, or at the very least, that our partner will not cause us purposeful harm.

Healthy intimate relationships involve partners who are mutually responsive to each other's needs. This means recognizing, understanding, and supporting each other, both in times of pain (e.g., losing a parent or a job) and gain (e.g., getting a promotion, announcing a pregnancy). 

After a certain point within a healthy intimate relationship, each partner recognizes a close connection and changes his or her view from "me" to "we." 

There is a mutual choice for wanting the relationship to continue indefinitely.

It allows for trust to continue to deepen, common knowledge to further be shared, mutuality to envelop, care to be shown, and continual effort be put into responsiveness and interdependence for both partners.
