When I discovered a money lie (something I was selling he acted as middle man and collected $$ for himself) I questioned whether or not this man was a psychopath. I'm serious. I didn't know how one could behave in such a way unless he had no conscience. Now I understand that an addict can, and will, do anything to obtain what he "needs". They act in ways against what their real selves know to be right.
PLEASE change your passwords, protect your money, hide your valuables. And hide them well (for me I dug a hole in the yard, put things into ziploc bag)
Another thing I discovered first-hand is that I was trying to be reasonable with someone out of touch with reason. It will do no good, if you ask me. You will just feel more frustrated, angry, and miserable if you confront him. He will just lie more and it will be fruitless.
Go into protect mode. Tell him about your filing when you know you are safe.
