Relationships - Is There a Need for Attachment?

Don't be attached to how I think the relationship should be. Instead, focus on how the relationship is. My wife and I have different political views. We have different religious views of the world. And that for me has been important in my relationship. If it's if it's planted, that's where it is. How do I keep it healthy? The point is how do I work with it in that non attached way?
