I admire you for walking away from the old T. He sounds like he could really hurt you. I would not want to risk seeing a T who had threatened to call the police like that. I know Ts do that when they are afraid that a client might hurt themselves, but in this instance it sounds like T was just trying to get rid of you.

I think it makes sense to not pay the bill just yet. Maybe in the future, but if it keeps you away from this ineffective and mean T, that might be a good thing.
