Casey This is manipulation. I know cause my X and I did it to eachother though not to the degree you are experiencing. It's a form or manipulation. Unless I deal with another manipulator (current business owner I contract with) I ceased and desisted since my past behavior is an embarassment at best.
A short excersize in discussions of these types. He who asks the questions controls the conversation. Example.
"If you went to a bar with a friend and he embarrassed you by making fun of you would you go to the bar with him the next weekend?"
Answer questions with questions. Do not make statements but formulate as questions where he is put in your shoes. This is a time of high emotions and you need to protect yourself.
Keep yourself grounded. Example H "See what you made me do!" Casey "So I have the power to make you do something? Don't you have free will?"
Try Keep the questions to where you know the answers. Little prep. Write down the statements. Best predictor of future events is past performance.
Best Wishes
