This man controls everything about you. Your home environment, your car. Which means he is well on the way to controlling you physically because he is literally monitoring your every move.
He is owning and controlling what happens in your own mind. Telling you how to think and feel, how you should speak to him. It seems to me, as an outsider, that you have lost you. Does he control finances too? You are pretty much his prisoner, OP.
There's no point in talking about possessions when you haven't committed to ending this horrific relationship. You're right to say you cannot change his mind. He is changing yours though, right down to what and how you think, how you process what you see with your own eyes.
None of this is your fault. This man is way worse than I initially recognised - and, believe me, he started off at disgusting psycho level in my estimation. I hope that you do intend, with the last of your independent breath, to end this. "The talk" is unnecessary. In fact, since all communication is under his control it seems a nonsense to "go there".
What disturbs me is that you are sounding very compliant about all this. I don't believe that you are impulsive or critical. This is your true inner voice trying to stop his abuse. I hope that his brainwashing - which seems almost complete - doesn't strip you entirely of the power to speak normally and naturally. But that point is very close. You are being used, exploited and controlled, OP. It is not your fault but it is your battle if you can find the strength to save yourself.
