I get the sense that he has consistently disregarded your rule of treating people respectfully. Do you have any guidelines or rules for your relationship that you and he have agreed to and have been followed over time? Your post reads like he sets guidelines for you but doesn't follow them himself. Or changes things midstream (which is fine when all involved agree but this seems more unilateral). In fact, he comes across as controlling. Is that accurate?
I would be worried and scared in your position too.
