I suspect it's a way of him justifying his actions. He's thinking "I don't want to be with kech because of her issues and I'm going to confirm that by getting a negative reaction out of her. When she acts that way, it totally justifies me doing affair stuff."
You DBing totally messes up his script and he also loses control over you.
I'm trying to think of more stuff, but I can hardly think right now. Sorry.
