Take time to pray through your areas of wrongdoing. Ask for God’s forgiveness, and then humble yourself enough to admit them to your partner. Do it sincerely and truthfully. Ask your partner for forgiveness as well. No matter how they respond, make sure you cover your responsibility in love. Even if they respond with criticism, accept it by receiving it as counsel.
