I took in a friend (male) who was being abused years ago. The kid involved wasn't his. She stabbed him with a screwdriver.
Where we lived, whoever makes the call, the other one goes to jail automatically. He never called. She did, after she stabbed him and he fled for his life. The idea is to separate warrinf couples till they can cool off. It may seem unfair, but it works. If you get arrested, you can be held for up to 2 days without charge. Without more robust aocial support, the police are having to use that to save lives. Cause there's not anything else.
He never knew this, but after he got out she came around twice and it was me that put the fear of Jesus on her.
But then, she was nothing to me but a threat because she was unhinged, out of control, and unrestrained by any sort of impulse check. She also thought of my friend as property.
Also true that invited this unstable element into my home by sheltering him, which exposed both me and my own very young child to her potential violence. So you can imagine, I was not willing to be wishy washy in dealing with this situation. My primary responsibility was to see my sweet Urchling raised up whole and functional. This is the responsibility of all parents and they seldom reach adulthood whole and emotionally functional out of abusive environments.
I will tell you that how I put the fear of Jesus on her was not entirely legal. I could have gone to jail. What it was though, was effective and I was already aware that nobody would come to save us. We'd have to save ourselves. Same old same old. Another day in paradise.
