Maybe, but I think this is fundamentally different. Threesome Girl did not have a real motive against me. In fact, we were still drinking buddies when I learned what she had been doing this whole time. There was no love interest, no need for revenge, nothing to gain from doing this. Yet, she did. And even more puzzling: a lot of people helped her, she always had a lot of social support. She was quite brilliant at that. Maybe - maybe getting that support and recognition was the motive, but she already kinda had that before.
Exactly, I know some people in real-life, immediate family members, people I can't easily ignore even if I want to, who just loves to feed on drama.
I usually try to stay away from drama queens like my sanity depends on it, but when family members do it, not easy or (always right) to ignore them. I tried to explain, rationalize, reason with them and their drama ways; but it didn't help much.
I think drama loving people are kind of addicted to how it makes them feel.
