Your wife is not your child. Only a child needs discipline! If she had done something wrong, you are suppose to talk to her, to find out why she had done it, and then work together to find a solution to the problem. If you want to play father to her, you will lose her! Love is supposed to be a communicating partnership. If you tell her how much she had hurt you, or how much you disliked what she had done; chances are that she wont do it again because she wants to be perfect for you. You wont became perfect for each other if you don't talk to each other to get to know each other. If she knows that she had hurt you, she will hurt herself because she will feel like a failure!
