Need to belong

According to Maslow's hierarchy of needs, humans need to feel love (sexual/nonsexual) and acceptance from social groups (family, peer groups). In fact, the need to belong is so innately ingrained that it may be strong enough to overcome physiological and safety needs, such as children's attachment to abusive parents or staying in abusive romantic relationships. Such examples illustrate the extent to which the psychobiological drive to belong is entrenched.
