Individuals often experience the human limitations of their partners, and develop a fear of adverse consequences of disrupted intimate relationships.

Companionate love involves diminished potent feelings of attachment, an authentic and enduring bond, a sense of mutual commitment, the profound feeling of mutual caring, feeling proud of a mate's accomplishment, and the satisfaction that comes from sharing goals and perspective.

In contrast, passionate love is marked by infatuation, intense preoccupation with the partner, throes of ecstasy, and feelings of exhilaration that come from being reunited with the partner.

Distinguishing intimate (communal) relationships from strategic (exchange) relationships may also be a factor.

Physical intimacy occurs in the latter but it is governed by a higher-order strategy, of which the other person may not be aware.

There are three types of love in a relationship: passionate love, companionate love, and sacrificial love.

Sacrificial love reflects the subsumption of the individual self will within a union and is said to be expressed within the Christian Godhead and towards humanity.

An intimate relationship is an interpersonal relationship that involves physical and/or emotional intimacy.

Physical intimacy is characterized by friendship, platonic love, romantic love, or sexual activity.

One example is getting close to someone in order to get something from them or give them something.

That "something" might not be offered so freely if it did not appear to be an intimate exchange and if the ultimate strategy had been visible at the outset.

Two people who are in an intimate relationship with one another are often called a couple, especially if the members of that couple have placed some degree of permanency to their relationship.
