Isolating and causing Aaron to be estranged from his family.... the family is right to be distrustful of her. These are classic narcissist tactics and she has that particular narc look in her eyes. Run Aaron, run like the wind; but he won’t. Narcs are extremely charming and manipulating. Once she completely engulfs him in her web she will devalue and discard him like an empty beer can. Aaron will go through an emotional and personal meat grinder when she discards him.
Narcissism is brutal. The person always want attention and never gets enough attention. He has to be the center of attention and will do anything to get it: new clothes to admire, new trip to talk about, and new projects to affirm.
If Aaron’s family is not talking to him, then that is a strong statement. Brutal.
If Olivia is narcissistic, then it would take 5 minutes of talking to her to find out.
