Why do we have domestic-Violence in the Family?

Instead of husband or wife to remain from domestic-violence untill death please separate yourself and live your normal life don't mind what people may say about you because you are the one passing through that agony and not them that gossip, Don't mind them go on with your life. Remember dead person is dead, he /she cannot speak from the grave yard once dead so, the best decision is separate yourself or your children in that place, if you notice that your spouse are not ready to change their harmful attitude towards you or your children!
