The above link is to a site dedicated to men in an abusive relationship. I know the focus here is usually on the women who are being abused, only because that is the majority of the people who come here but I certainly know that men are abused also.
I took a quick peekaboo at this site and it seems like an excellent resource for men, honest and realistic. It give a safety plan for leaving, what to expect when you leave and how to deal with your abuser.
Hugs to all the men out there dealing with a narcissistic woman, I hope this is helpful.
