Joanna, I will suggest that you carry a short whip with you when you go in to feed. I like the one at the feed store made for swine; it is shorter with a little paddle-thing on the end. You can cue Mr Smarty to stay out of your space unless invited, and that you are the boss of his feed bowl. The beginnings of a bond are mutual respect. You can use the end to scratch withers also. I have a bossy boots and we have to have a respect lesson over the food dish once in a while. I stand in front of it, and do not allow him to eat until I move away. You don't need to say anything, just use your body and the whip to make him wait. I would also stand there for a little while, just so he knows that he is eating with your permission. If he tries to get bossy, shaking his head at you with his ears back as he is eating, drive him away from the food dish again. Just takes a few times and you will both be happier.
I would never allow him to rear up at me. If he does that, lunge toward him waving your arms and shouting. Make him back up until he sees you are not interested in that dangerous game. Once he stops, stand quietly and then walk away.
