Yes, there's history. Too many unconnected adults have had a say in his early life, telling him who he should and shouldn't listen to. It seems to have diminished the role. I suspect the imposed responsibility has overwhelmed him.

His relationships are transactional. Whether he has the potential to develop deep bonds, he doesn't. He has said that most people are essentially selfish and untrustworthy.

At times he is sensitive and reactive, sometimes avoidant, and occasionally violent. He makes plans while disregarding the well being and rights of those around him. I don't know whether he understands but when questioned he tends to say it's the other person's fault.

He has a history of stealing from people close to him and destroying their property for the purpose of control. He also spies on people when he thinks they aren't looking.. or are asleep.

He is heavily dependent on pot, and most of his relationships and daily activities are based around that.
