I recently wrote: "First, let’s examine what makes for a healthy marriage. Any healthy relationship stands on an interdependent foundation. What do I mean by that? The parties to the relationship share goals. They each view the other(s) as having something to contribute to those goals for everyone’s benefit. The contributions do not have to be equal but the expectations of all are understood— they don’t keep score and have no hidden agendas. They do not have to agree on everything and they can disagree, even often. That’s ok — they respect each other's boundaries, values, and priorities. No one belongs to or feels subservient to another. Through open and vulnerable communication, they hope to share their completeness with each other and yet know that they can continue to grow. No matter how complete, no one has achieved perfection."
As I see your style, you may appreciate the fact that I did not say that in a relationship advice article. I don't write those but the topics do come up. I wrote that in an essay about how humanity would benefit from marrying science, spirituality, and philosophy as equal or almost equal disciplines in the search for truth. https://medium.com/@marcus17043/m%C3%A9nage-%C3%A0-trois-between-science-spirituality-and-philosophy-a634f5446364
