And yes, when he pulled over and you talked to him he did use you
1. He learned he can still manipulate you 2. He diffused your exposure efforts
When you talk to him in public after your exposure, NO ONE will take your exposure SERIOUSLY after that... and HE looks BETTER...
He WANTS people to see YOU talking to HIM, it makes HIM look better and not the jerk you exposed him for... to YOU that may nto be the case and even to the public at large, but in HIS mind, if you talk to him after exposure and him moving out then it diffuses you exposing him to HIM and HIS mind...
And yes, you cut him off before it got worse, but he did get something out of the exchange, he always will... as will you
