Sometimes they don't turn that way until marriage and kids. Everyone is a great psychologist until it's their turn. Everyone have a plan until life smacks them right in the mouth. The cops don't need to determine who right or wrong in domestic situations. They can lock up either party or both. Remember that. You can slap someone's hand away from your face and the cops have all the right to lock you up for that action. Remember that! Don't judge. Creating an absolute rule not to hit women could apply to frail skinny man as well.
The size of the man makes no difference. I'm married with kids and if my wife turned violent, she'd be gone. Having kids or being married doesn't excuse domestic violence. You really think you're doing your kids a favor by staying in a violent home? You can try to justify it all you won't but hitting a woman isn't acceptable to me.
