Answer:
Intimacy vs. isolation
Step-by-step explanation:
According to Erik Erikson, when an individual becomes a young adult, around age 18 (or older) he enters the stage known as "Intimacy vs. isolation."
In this stage, the interest, besides professional, gravitates around the construction of deep and lasting relationships. One can experience moments of great intimacy and emotional surrender. Should a disappointment occur the tendency will be temporary or lasting isolation.
