burned by peer pressure & instagram

So I buckled to a 'friends' insistance to look her up on instagram (a media which I find offensive as its chocked full of N's). Of course xN and OW (whom he charmed into leaving her country and job via online dating while he & I were together 8 months ago) follow this now-former-friend (who is thoroughly captivated by N, whom I introduced her to). I broke NC by clicking one of their pic links as curiosity got the best of me since the last names were the same. xN & OW just eloped. Back to recovery square one... crap. (no, I did not 'contact' anyone of them).

What I don't get is (1) why did this former-friend bug me to check out that media after I divulged that he's a N, abused me & destroyed my life... she admitted that she gets it, admits now that I was not the psycho and is glad I got away. She knew I'd see them so how psychotic is that!? (2) how can she stomach being around him... yes, I know the answer to that one.

Conclusions: NEVER go against your instincts and break ALL contact with ANY joint connections! I would like to feel sorry for the poor young Brazilian pawn that he just bought, as she is up for a life of hell.... but that's their story not mine.
