You probably hit it off right away, feeling very comfortable in one another's presence and sensing a natural affinity from the start. Conversation just flows between you, and your lover makes you laugh and excites you with the new ideas that they bring to the table. You feel a sense of understanding and rapport with your lover from the start, because you're naturally attuned to them emotionally.
Your creativity is enhanced through this relationship because you are able to support one another so well. Emotionally or professionally or both, you inspire one another; through communicating with each other, you feel creatively stimulated and come up with bigger and better ideas, maybe more so than ever before. You're both individuals, of course; your partner has a naturally more dominant personality, and provides the energy and excitement that drives those big ideas, while you are naturally more sympathetic and provide more encouragement and intuitive support. You each support the other in your own ways. As this relationship is so comfortable, take care that you don't end up taking one another for granted. This should be carefully avoided! Though it probably has been easy to settle into a groove together emotionally, relying on one another for that natural rapport that you both come to expect, you should both strive to remember that your connection, though seemingly effortless, is a gift to be cherished.
