The phrase "best friends first" highlights the importance of building a deep and meaningful friendship with your partner before adding the romantic aspect to the relationship. Friendship forms the basis of trust, understanding, and compatibility, which are essential for a strong and lasting connection.
The addition of "and a couple second" suggests that the romantic aspect of the relationship should come naturally and complement the existing friendship. When two people are best friends, their romantic involvement becomes an extension of their emotional bond, making it more genuine and harmonious.
In essence, this statement advocates for the idea that a romantic relationship is at its strongest when it is grounded in a solid foundation of friendship. It encourages couples to prioritize friendship, as it fosters a deeper connection and mutual understanding that can withstand the tests and challenges that relationships often face.
