I would advise against this course of action. You can not make a narcissist feel the following things: regret, shame, pride in someone else. If she cant degrade you with truth, then she will do so will lies while putting up a confident face. You're just setting yourself up for more mental exhaustion.
If you're really need to get back at her for what she did to you then do so from a distance where she cant reach you but can definitely see you. Nothing pisses off a narc more than seeing their nsupply thriving and doing better than them.
Seeking happiness is the best form of revenge.
