After being married for 38 years, having a long hard very difficult marriage, and being in a Christian marriage, my advice to you is to make sure that your marriage is found on faith that God has brought the two of you together. When love fails, or becomes weak, which in time it may, you must have your faith to rely on to keep your marriage together. You are not promised all good days and sunshine. You may have many hard times in your life. But to keep your marriage together, make sure your marriage is grounded on faith in God, and that you both know that it is HIS will for you to marry. Then, when the storms come, you can live by your faith.
