One of the leading causes of conflicts in relationships is the way we react to each other. If your spouse is upset, and says something that bothers you then you might react to his or her negative emotions. But whenever you react, you are empowering that negative emotion and you are putting that person in power over your emotions. But when you respond thoughtfully, prayerfully, and in your own time and in your own way then you are empowering the Holy Spirit and you are placing yourself in control over your own emotions. That is the best way to prevent arguments and work through conflict.
