Before you decide to leave therapy (or not?) it might serve you well to let him have it verbally. That you feel Like his friendliness might have been fake all along. That you can’t trust what he says. He needs to know this is a serious rupture and he needs to hop to it on the “repair” part before he loses you. Maybe he will step up to the plate and come through. Are you able to contact him between sessions? If so you could even tell him you are thinking about quitting and you are holding on by a thread. I’m all for blasting these guys when they screw up. The good ones will make it right and not ignore your pain.
