Arianna is the worst of the worst when it comes to Narcissistic Abusers. I understand that people think they’re the exception and won’t be subject to her manipulation and lies but she uses EVERYONE in her life. I’ve seen it with my own eyes. Her son, her sister, her mother, you name it. There is no one in her life that she isn’t treating like the next sucker she can take advantage of. It may be for direct gain (gifts, emotional validation, sex, etc) or to use against others who she sees as a threat because they aren’t buying in to her delusional bullshit.
If you’re determined to expose yourself to her understand what it is that you’re dealing with and be prepared to protect yourself.
Here is a list of videos I recommend you watch. Keep an eye out for the warning signs.
