“What could I do? There wasn’t anything I could do? I couldn’t stand up against him!”
Actually, you could, can and should have.
I have had several battered women seek shelter in our home and to a man, their abuser backs off when they are confronted. I have been told it is because I am male.
That might be true in some, but not all cases. It is the thought that their despicable behavior is now known to another and s/he will call the police.
Here is an incident shared by the clinic of a battered woman seeking help from the female staff. She gave them a note stating that her boyfriend was an abuser and had a gun. The couple were waiting in the examining room for the vet.
