Narcissist ex want me back, break up and new, I was building with another person

It's important to note that I can't provide specific insights into individual situations, but I can offer some general information on narcissistic behavior and why a narcissist might try to disrupt your new relationship.

Need for Control: Narcissists often have a strong need for control and attention. If they see you moving on and building something new and meaningful with someone else, it may threaten their sense of control over you. They might want to regain control and disrupt your new relationship to keep you under their influence.

Ego Boost: Narcissists thrive on admiration and attention from others. If they see that you are happy in your new relationship, they might want to re-enter your life just to boost their ego and feel like they still have a hold on you.

Fear of Abandonment: Narcissists often have a deep-seated fear of abandonment and rejection. If they sense that you are moving on without them, this fear can be triggered, prompting them to try and bring you back into their orbit.

Manipulation and Power: Narcissists are skilled manipulators and may use emotional manipulation and power plays to disrupt your new relationship. They may employ tactics such as guilt-tripping, love-bombing, or gaslighting to regain your attention and affection.

Lack of Empathy: Narcissists typically have a limited capacity for empathy, making it difficult for them to consider your feelings or the impact of their actions on you and your new partner.

It's essential to recognize these patterns of behavior and prioritize your emotional well-being. If you find yourself in a situation like this, consider setting boundaries, seeking support from friends and family, and possibly consulting with a therapist or counselor to help you navigate the complexities of dealing with a narcissistic ex-partner. It's often best to prioritize your own happiness and mental health in such situations.
