A LDS mixed faith marriage often means the loss of certain dreams. There may be many lost dreams: the dream to be senior missionaries, to attend the temple together, and to raise kids in the church together. Here I talk about the loss of dreams through the lens of codependency.
The loss of a dream will trigger the grief cycle. When you can allow the grief cycle and work through that process you can end up in acceptance.
Acceptance is the key to moving forward in your relationship when dreams are no longer viable.
