Usually drawn as a triangle, with the point down and the "victim" on the bottom.
The top two corners are a Rescuer (or co-dependent / enabler), and the final corner a Prosecutor (or Villain).
When *we* do not enable or co-die or rescue the wantabe Victim Status for Life A/A, etc. they try to move us from the Rescue Role to the Villain Role in their fantasy.
You have seen this basic plot for years. Basis of the Disney Princess. Victim Princess at the bottom, Evil Witch / Villain trying to harm them. Prince Whatever there to Rescue. Basic Drama Triangle.
Same game the Alkie, Addict, Borderline, and the rest of the mess try to carry along and project from their Addict Mind.
