There is little anyone can do in this situation if indeed he is a narcissist. He is then on a level of sociopath perhaps not full-blown but none-the-less a sociopath for all intent and purposes. My experience with a sociopath (and we all know one or two ) and my studies of the condition is the conclusion that sadly is they cannot be cured and they don't want to be. They are only in it for themselves and create disaster for everyone else and do not care that they do. They lie and steal without conscience and the only thing a person can do is turn away from them and not look back.
Search the Internet for more info and especially Dr Robert Hare who has compiled a list of their recognizable symptoms. You cannot win and will lose with a sociopath. Not all sociopaths are serial killers as some might think but all serial killers are sociopaths. In the top ten career choices of a sociopath "surgeon" is one but not "doctor". Why? A surgeon has no emotion about cutting a living human with a scalpel while a General Practitioner might find it too gruesome.
The choice is yours though and my opinion is based only on your description and my experience. Only you know in your heart what is right. Very tough emotional position you have been placed in, very tough indeed but time does heal all wounds
