What you most desire in a relationship is continual growth and development.
Therefore you should avoid a lover who wants to settle into a warm, comfy, secure relationship. Seek a more adventurous person who is always looking for new ways to make your affair more spicy and keep it in motion.
The true test of a happy relationship is whether each of you can steer the right course between evolution and stability, avoiding the reefs on both sides.
If you can steer that course, you will indeed be an explorer in the realm of emotions and interpersonal communication, and you will learn a lot more than most people about what makes a relationship good or bad.
If you and your lover are creative and mutually responsive within your relationship, your love will be a continuously exciting adventure.
