How to write about married life in an autobiography
Write a clear objective describing what you want your autobiography to do for the eventual reader.
Based on the objective, create a list of moments in your married life that, when described, will help achieve the objective.
Be sure to note what you learned from each of these situations.
Run the list by your (current or past) significant other. Ask them to describe the events in your list from their memory.
