Yes, it's not uncommon for narcissists to speak poorly about their previous partners or "old supply" to their new supply or current partner. This behavior serves several purposes for the narcissist:
Isolation and Control: By painting their previous partners in a negative light, the narcissist attempts to isolate their new supply from anyone who might provide a different perspective or share their experiences. It helps the narcissist maintain control over the narrative and the perception of the past relationships.
Smear Campaign: The narcissist may engage in a smear campaign against their ex-partners as a way to damage their reputation and credibility. This further reinforces the narcissist's control and manipulates the new supply into believing that they are the superior, more reliable partner.
Ego Boost: Speaking negatively about their old supply may serve as an ego boost for the narcissist. It allows them to feel superior and reinforces their self-image as the victim or the one who has been mistreated.
Deflecting Responsibility: By blaming their previous partners for the failures in past relationships, the narcissist avoids taking any responsibility for their own behavior or the problems that contributed to the breakups.
It's essential to recognize that these behaviors are part of the narcissist's manipulative tactics, and they often do not reflect the reality of the previous relationships. When a narcissist targets a new supply, they are likely to use similar tactics against that person when the cycle repeats.
If you suspect that your narcissistic ex is spreading false information about you, it's important not to engage in any arguments or attempts to defend yourself. Trying to reason with a narcissist or correct their false narratives often proves fruitless. Instead, focus on your own well-being, surround yourself with supportive people, and consider seeking professional help to heal from the emotional effects of the relationship. Therapy can be beneficial in understanding and recovering from the manipulative dynamics of a narcissistic relationship.
