Perhaps reciprocity is the most important element in any relationship weather it's friends, family or your life partner. Being in a relationship where one side is giving much yet not receiving the same energy back can be quite a painful experience. The equal exchange of effort would serve as building blocks for emotional intimacy and trust, otherwise resentment would build up over time.

Your bid for connection is vital " whether it's verbal or nonverbal, small gestures, cues, or expressions of a person's need for attention, or validation".
