My sister was also a victim, but I'd bet you couldn't tell, to look at either one of us. We are stable-minded adults, on the exterior, and we lead our lives without a hitch. I went to school every day and no one even fathomed that I was a victim of domestic violence. My best friend didn't even know, at the time. Because we are taught that you don't talk about it.
Domestic violence is a dirty little secret that can destroy the lives of everyone involved.
For the longest time, I was angry at my mother for taking her abusers back, but I shouldn't have been. I know now that I should have talked to her instead of at her. If weak minded means scared, then yes, battered women are weak minded. If weak minded means they have nowhere else to go, then yes, they're weak. If being weak minded means they're scared they won't be able to support their children, then yes, they're weak.
