All couples go through hard times.
When you ask happy couples about the story of their relationship, they tend to "glorify the struggle." They talk proudly about how they've overcome their challenges together. There is a strong sense of "we-ness" in the relationship.
When you ask unhappy couples the same question, they tend to feel resentful of their challenges. There is more disappointment than satisfaction. There is more "me" than "we."
How do you tell your story?
