You and your spouse are getting a divorce, but you have both agreed that you want to have a good relationship for the sake of your children. Neither of you did anything particularly wrong to cause divorce, but you grew apart and simply weren't happy any longer.
As a result, you want to build a strong coparenting relationship. To you, this means that you can still share holidays and events together. Perhaps you can even travel together as a family, but you and your spouse won't have to be in a marital relationship any longer. Of course, this kind of relationship takes work, especially when you're ending a marriage.
