Indeed, it was as individuals that you were drawn to each other. You fell in love with another person, with the strengths and weaknesses and quirks and dreams of that other person. If you lose sight of who you are as individuals, then you lose the basis of your relationship. Continue to expand and grow, and honor the full stature of one another. On the other hand, remember that your relationship also has its own needs and goals.
Marriage is a living, breathing organism.
It has a nature and attributes of its own that are distinct from those of the individuals it comprises. A relationship has its own mysterious sense of balance, its own timing, choreography, and destination. Be kind to your relationship. Treat it with respect. Nourish it with the entertainments, diversions, mementos, and happy anticipations it needs to keep it young and kittenlike.
