No, stay out of it, if the slag is dumb enough to stay with a man who beats her then tuff tits for her. It will only end up turning sour on YOU and YOU will be made to look the prick when she just goes back to him anyway. If a couple of punches from her OWN man isn't enough for her to leave him, what makes you think you getting involved will?Let her get on with it, she might for some reason deserve it, you never know. Or she might even be one of those sadist macho bitches that enjoy it.
