While I don't have access to specific information about your ex or their intentions, I can provide some possible reasons why your narcissistic ex might not have deleted your number despite the breakup:
Maintaining Control: Narcissists often want to maintain a sense of control and power over their former partners. By keeping your contact information, they might feel like they still have a connection to you and can reach out if they choose to do so in the future.
Seeking Attention: Narcissists thrive on attention and validation. Keeping your number could be a way for them to hold onto the hope that you might reach out to them or that they can get your attention if they decide to contact you.
Using it as Leverage: Having your contact information could be seen as a potential advantage for them. If they ever want to manipulate or influence you in the future, having your number handy could be useful.
Avoiding Closure: Narcissists may struggle with accepting the finality of a breakup and might not be ready to let go completely. Keeping your number allows them to maintain a connection, even if it's just one-sided.
Hoovering: In some cases, narcissists engage in a behavior called "hoovering," where they try to draw their ex-partner back into the relationship after a breakup. Keeping your number would facilitate this process if they decide to attempt it.
Monitoring and Surveillance: Narcissists might want to keep tabs on their ex-partners even after the breakup. By holding onto your contact information, they can keep an eye on your online activities or gather information about your life indirectly.
Remember that each individual is unique, and the specific reasons behind their actions can vary. It's essential to focus on your well-being and healing after a breakup with a narcissistic partner. If they have not contacted you in almost a year, that could be an opportunity for you to move forward and create a healthier and happier life without them. If you ever feel uncomfortable or unsafe due to their actions or behavior, consider blocking their number or seeking support from friends, family, or a professional counselor.
