Any marriage problem is like a soccer ball that the two of you are kicking around. You work together, figuring out how to get it down the field.
But it isn’t just your problem, or your partner’s. It belongs to both of you. You’re on the same team.
When it comes to problems in your marriage, try to look at them objectively as projects that the two of you are going to keep working at in a collaborative way. Working together, even if you don’t always make much progress, will build trust and understanding. And that will keep any given problem, even the unsolvable ones, from harming your relationship.
