In Karpman’s drama triangle there are three roles: the Victim, the Persecutor and the Rescuer. Two versions of the triangle exist; the narcissist’s version and the objective reality version. The narcissist sees her- or himself as the Victim, the person they’re abusing and exploiting (the old supply) as their Persecutor and their new supply (e.g., the mistress/manstress) as their Rescuer. In reality, the narcissist is the Persecutor, the new supply is their enabler/accomplice (unwittingly or wittingly) and the old supply is the Victim. At the beginning of your relationship with your narcissist, when you were the new supply/Rescuer, you probably aided and abetted your narcissist in hurting your predecessor. You were once the hero or angel, and now you’re the big old meanie who doesn’t appreciate your Narcissist anymore. The new supply is the answer to the narcissist’s problems just as you once were. Rinse, wash, repeat.
You may be cast again in the role of the Rescuer if you’re foolish and self-destructive enough to hang around and wait for your narcissist to become disappointed or bored with the current new supply. But remember, even if that happens, the narcissist will only become disappointed or bored with you again and around and around you go. Just step out of it.
What about the new supply/Rescuer? She or he is most likely another hapless codependent who sees your narcissist as a poor, downtrodden, unappreciated victim. Don’t envy the new supply. The narcissist will do to them what the narcissist did to you. Alternately, the new supply/Rescuer may also be another narcissist, borderline, histrionic or sociopath who saw your narcissist coming from light years away and then mutual love bombing commenced. If the new supply is another disordered predator or conniver, the two of them will eventually cannibalize one another, in which case maintain a safe distance and pop some popcorn. Or, you can heal, move on with your life and not look back. Okay, okay, enjoy a little schadenfreude then move on and don’t look back.
