I don't get it.

The title of the article is "To Stay in Love, Sign on the Dotted Line," but there's absolutely nothing in it that supports the title. All it is is about an unmarried woman whose been in a relationship for only 3 years saying a scheduled conversations and paper an pen (or keyboard in this case) helps her have relationship communication.

The title should really be "communication is helpful for my new relationship."

It's misguided at best to conclude every couple should create this sort of formal contract. Every couple communicates differently.
