In my experience the narcissist in my life walked away with all the family and friends. They are master manipulators and extremely charismatic. They tend to place themselves at the center of attention and surround themselves with those who if not one of their hand picked hangers on would be treated as unworthy.

Be prepared for him to be painted as the victim. Be prepared to be cut off as people pick his side (they can't help it).

But is this not worth being free of the cycle of abuse?
