Forgiveness is one of the answers to how to fix a broken relationship. Holding grudges will only damage a relationship. If you feel contempt towards your partner regularly, and you can’t find any resolution, it can cause serious long-term challenges for your marriage. There’s power in forgiving, especially when you can do it quickly. Remember that forgiveness is a gift to the person you forgive, and to yourself. Don’t hold grudges that will only eat up your emotional and mental space.
