I know you mean well by testing this guy Arthur, but I would be inclined to not even waste the time and heartache on this immature guy.
If Ghee has been drawn into believing his stories, and been manipulated to think she must do what he is asking, then she might be again talked around to believe anything he tells her. This could mean that she is left hanging on for a guy who clearly wants his cake and eat it too.
Move on with your life I think is the best advice for this young lady.
