Narcissists will try to suck you back into contact with them. Resist it.

When a pathological narcissist is out of your life, they may eventually try to “hoover,” or suck you back into contact with them. Hoovering may be done by emailing, texting, calling, or snail mailing. A narcissist may send you a long email or text “hey.” Hoovering is practiced by a wide range of narcissists—family members, friends, co-workers, employers, former spouses, and significant others. It is usually preluded by the narcissist needing to fill their narcissistic void or a bottomless pit of need—in other words: it’s not about you. Don’t respond to a hoovering attempt.
