Sally says she’s done with the relationship. She claims Charles is a “drama queen” who “thrives on attention” and that he has been abusive toward her.

On Friday’s episode of Dr. Phil, the couple gets into a heated discussion about Charles’ behavior, specifically a time that Sally claims Charles choked her.

“I'm full of mistakes myself, but I'm willing to admit that I have psychological issues and problems, and I'm willing to do whatever it takes to fix them,” he tells Sally.

“Those are not mistakes. Strangling somebody is not a mistake. That's something that's deliberate. That's like attempted murder,” Sally responds.

“I didn't deliberately try to kill you; I was trying to overpower you,” Charles says.

Dr. Phil interrupts the conversation and offers Charles a powerful warning.

“There is no time, no theory, no justification, under which a man should ever put his hands on a woman in anger. Period, paragraph, no exceptions. No reason,” Dr. Phil says.
