This combination is usually a difficult one. The moon rules Cancerians, making them moody, sentimental and secretive. Their tendency is to live in the past, and they have a difficult time forgetting serious quarrels or disagreements that occur early on in the marriage. Ever heard the saying, ``If you make it through the first year, the rest is easy?`` This is true of this couple. The secretive nature of Cancer clashes with the openness of Aries, who on her part can be moody too. What happens when you get two moody people to live together? Chaos or balance, depending on whether one can counteract the other. Aries may try to keep moody Cancer in high spirits in order to maintain harmony. Though the reverse could also happen, making the entire proposition highly risky. What may be of little concern to an Arien may be very traumatic to Cancer. Though Cancer holds on with the tenacity of a crab, he has a tendency to back away from situations that have been hurtful in the past.
