I'm thinking right now about the phenomenon known in narcissistic pathology as "hoovering."

It's when the narcissist knows you're about to leave him, and he gets on his best fake behavior to keep your attention.

If it succeeds, the abuse that rains down on you for trying to leave is worse than anything you've seen before.

I know everyone needs $2k, and I'm telling you something's not right. Something's really really really not right.

To wit:

"During the process, the narcissist abuser may employ virtually any means necessary to obtain their desired result: the return of the victim to the abusive relationship."

"These ploys can include attempting to put the victim on a guilt-trip, generating false promises of changed behavior, false promises of too-good-to-be-true gifts, begging, screaming at the victim, use of relationship shame, making threats,..."

"...insincerely accepting blame for the failure of the relationship, or even using others (flying monkeys) to help persuade the victim to return to the relationship."

"The abusive narcissist is on a no-holds-barred campaign to convince the victim to return to the abuse and their abusive clutches."

"The ploys are only limited by the narcissist's imagination. Some of these ploys may include: ...

Sending gifts for no reason. The abusive narcissist may send flowers, cards, or other gifts as a way to reach out and tug at the victim's heartstrings."

"One must understand, narcissists are in a relationship for one reason — to get what they want from the victim — and they will do whatever they feel necessary to get the victim to return to the abuse using false and manipulative means."
