I think part of it is that he's unable to assert himself with "organic" women. I agree that he has control issues, but I see it stemming more from his history of feeling out of control with his previous partners.
He's unable to handle the unpredictability of a relationship with another person or the lack of control over their actions, so he resorts to dolls who can never question him. The fact is that the article scares me a bit, since I can totally see a lot of people being attracted to dolls to escape the maturity, responsibilities, and skills needed to deal with real people.
In all honesty, I would recommend getting professional help if the issue has become so serious that you're afraid of losing control. There is a stigma against going to therapy, which is unfortunate since refusing to go see a therapist when you're emotionally unhealthy is the equivalent of not going to a doctor when you're physically ill. You can live without the help for a while, but it will become quite hazardous to your health if you don't resolve it.
I have had anger issues, although I never had rage episodes. It sounds to me that something in your life triggered this event, and that trigger may have reminded you of an earlier event in your life in which your response was to suppress your anger and hurt. This is just my guess though, but I would highly recommend you go to a therapist or even call a help line to talk things out.
