Is he going through personality disorder or something what is up with him

He does displays some deeply self defeating traits such as an intense need for control, distrust, emotional detachment and manipulative tendencies...but I think a lot of his behaviour is rooted in his traumatic past, fear, shame and deeply distorted understanding of intimacy (especially when it comes to his relationship with Michele). He's a psychologically complex character...and while his trauma helps explain some of his behaviour, it doesn't excuse the harm he causes.
