Kelly had this to say about it
"Many have asked for an update on Zach and Sarah’s courtship that was announced last June. After prayer, Sarah decided to end the courtship several months after it began. We have not posted any updates or answered any comments about it until now, in order to give both Zach and Sarah time to heal.Any parting of a relationship causes pain, and although we would love to avoid heartaches in life, it is through these very trying times that character and faith often grow. For Zach, it has been a time of learning, thinking, and drawing closer to Christ.Zach is grateful that he and Sarah hadn’t chosen the traditional path of dating, since it protected them from wrong goals and further pain. The three main goals of their courtship were 1. to maintain purity, 2. to discover if they were the right life partners for marriage, and 3. to honor God first and foremost in their relationship. In that sense, their courtship was a success, as they achieved each of these goals.Although the relationship did not progress into engagement and marriage, their time together was focused on strengthening their walk with the Lord, and therefore ended in friendship. Zach is grateful for having developed a relationship with Sarah and her family. He has learned valuable insights from the example of their family harmony and love for God. In spite of the pain of parting, he is full of memories and experiences that have encouraged him, strengthened him, challenged him, and humbled him. He can appreciate the growth that has taken place in his life as a result of these circumstances.Thank each of you for your prayers and thoughtfulness!"
What is the difference between a break-up in dating or courtship? I can see no difference.
