Boundaries are a huge issue in abuse. Some infer that the victim isn’t setting boundaries, and if they’d just set boundaries, the abuser would know he couldn’t cross the line and would stop.
This is not true in most cases. Many abusers not only throw temper tantrums in the face of boundaries, but also see boundaries as a dare to violate them, and ramp up abuse when boundaries are set.
Boundaries are definitely needed, but not at the cost of your safety.
