Exposing the Narc?

What do you think about exposing the Narc? Since my xN married the OW (well, actually I never knew which one of us was the OW) I can almost feel her pain. I know what she is going through. Plus, she is so much younger than me (and than him), he is biting tender flesh.

I know I can't go to her and say 'Hey, your husband is a Narc, see what he did to me'. That doesn't work. She would circle the wagons.

Actually I don't need her to know about 'him'. I just want her to know about Narcissism, and draw her own conclusions. Like, when I became aware of the concept myself, everything changed.

So, this is what I did a couple of weeks ago. I made sure she got exposed to the idea of Narcissism and the existence of this very website, in a way she won't even know it comes from me. It's magic - just one word, and it leads to internet search, then to understanding, then to healing. Becoming aware saved me. Maybe now it can save her. Probably, I'll never know if it worked, and I won't even know if she is reading this, but I do feel better.

Exposing a N it's never easy, as people just see their charming and lovely mask, and it will only make us look bad. What do you guys think? Has anybody tried to expose a N and how did it work?
