Survivors of violence stay for a multitude of reasons, be they financial, religious, fear, and more.  Survivors of violence are more likely to die after they leave the violent relationship and the perpetrator has lost all control/access to them.  We must stop asking "Why didn't they just leave" and instead start asking the real question of "Why perpetrators of Domestic Abuse choose to abuse"? Because Domestic Violence is always a choice that is being made by the perpetrator.
