I don't think you can make him see things the way you do. He needs to come to that on his own.

You *can* start to practice setting better boundaries for yourself. Figure out how to not get bothered when he pouts when you don't want to do what he wants. Start doing what *you* truly want to do and don't let his nastiness interfere with your happiness. He may even start behaving better when he sees that his nonsense isn't having the desired effect.
