Oh please please read my post on Gaslighting. In it is your salvation. I just got out of the EXACT same thing. Never confront him with evidence, he may get psychotic. Had he had episodes where it seems like he's lost touch with reality? Best thing is to give all the evidence to a divorce attorney while securing custody of your children.

You are the victim of a narcissist. His goal is to make you dependent on him as he only seeks control over what you think and feel. Don't react to the obvious BS he hurls in your direction. Your reactions feed his ego. Not reacting and being indifferent will drive him insane. Get a video camera for evidence.
