Call the police.
I think you have a neglected case. Good luck.
But I would go up and kiss him on the cheek. This is the best manifestation of love that is on Earth. It is worth noting that people who criticize you are rare, they should be valued as the most valuable. Thanks to them you have a chance to become better. You can put your pride in one place. I would even raise it to him. With a salary, give him $ 20 ... If you beat, allocate 50. He's your best entertainment for the next month...
Оn the other hand, maybe he should pay you extra. Understand who will humiliate whom. And who to whom to pay.
The next time he comes up, put 1-20 dollars on the table. And tell me, I'm ready to pay you for your criticism ... When it's really destructive. At your price of 1 cent. But I give in advance.
And smile)
