This woman was obviously very frightened because she had already been a victim of violence and had made that huge decision, ( not before time) to leave.
Was she in danger, I would say yes, as it takes a nanosecond for someone violent to become violent.
I cannot help but wonder where in the world domestic violence is taken truly seriously. Trouble is with victims who believe their abuser being contrite afterwards, or are simply too afraid to leave.
It is an awful situation, but I still think that the gendarmes should have gone with her.
