You kind of did it again. You told him what YOU think HE should do like go to his parents, kind of made a sarcastic remark about the envelope, brought up his behavior from last year's Christmas and brought OW into the conversation.
Stop and try not to react to his words/actions. He does it because he knows how to get your goat.
