i like my movement in life.
To my mind, fighting with the woman would not bring any use to you. You will just express your negative emotions. And also it would develop an unsurance to you and she would not trust you anymore. As the result, It would kill her love to you. But, from the other hand, if the woman cheats you, it men's that you have missed something important in your life together, or that she doesn't love you anymore as much as she used to. I think that the best thing in such situation is to come down, sit together and discuss everything without any strong emotions. In such a way, you would find out the problem and would find the solution.
