Hank started young and threw himself into his work. We know nothing of his father, except that at this point he must have been dead for a long time. His mother and brother are total leeches and in that kind of family, he would not have known that manipulation - as a substitute for actual family love - is NOT the norm. Hank's focus was on producing and succeeding. At this point, he doesn't KNOW real love or real friendship and, apparently, doesn't know that he doesn't know.
Strong people who think for themselves are often the victims of their own families when that family bond is not nurturing but toxic and destructive. That is the hardest bond to shake off, but some times the most necessary. Hank needs an awakening...
