There is a third option. If someone is habitually abusive, document the abuse via a hidden camera and then go see an attorney. What judges need is evidence.
It is just plain stupid to stay with someone who is habitually and dangerous abusive. I know I offend DV victims when I say this but really the only sane option is to leave. If you don't leave you are either so battered that you cannot make decisions or you are just plain stupid. Do what women do and take the kids and go.
People who value the property more than their children's well-being are not responsible parents. So you take a financial hit? Your kids will forgive you for that. They won't forgive you for bringing them up in a violent home. If you are one contributing to the violence, they won't forgive you for that either.
