"Why did you betray my trust by hiring the most aggressive D lawyer in town to file a petition without telling me about it first?"
He's really mad that you've pulled the rug out from under his feet because you've one upped him in this area in protecting your intersts. This suggests that there's a real underlying fear that he'll NOT be able to control the outcome of the D proceedings in his favor. Hmmmmm. He hates losing control of this process. So he is shifting the blame on to you. Isn't that interesting?
