Mercury represents our communication style and intellectual processes. Strong aspects between your Mercury and your partner's planets and/or points favor communication and sharing ideas.
Mercury Square Jupiter
You use your relationship to expand your consciousness as you bring out your partners adventurous side. You have a tendency to have great ideas but find it easy to get the two of you involved in projects that either grow too quickly or somehow become unmanageable. If your partners Mercury is square your Jupiter, your optimistic attitude and good luck bolsters your partner through the tough bits with a witty sense of humor and a philosophy that finds opportunities in what others might consider abject failures. Its all a learning experience, and the two of you are definitely students of life, so youre up for it.
