I suppose that you are referring to this text below.
My father always tells me: "Conflicts in a marriage are a sign of no "the" here normality and happen even to a perfect couple." And he adds: "Do not try to fully understand your wife as you are doomed to fail." Men and women are too different to be able to live without any misunderstandings, and at the same time they need each other so badlyin order to live a happy and no "a" necessary here complete life. Unless, of course, someone chooses to be single. Disagreements are also required for a relationship to grow and become stronger. My suggestions are in red.
