I do this all the time. With my husband, our children, a close relative, a friend. Sometimes I just randomly get an incredible overwhelming feeling and am reminded of his much I love them and how blessed I am to have them in my life!
Forgiveness doesn't excuse their behavior. Forgiveness prevents their behavior from destroying your heart. Deciding not to forgive hurts not only the other person but you as well. Not learning to forgive hardens the heart and makes shallow the soul.
