This combination is usually hard to match. The moon rules Cancer, making her moody, sentimental and secretive. She tends to live in the past, and has a difficult time forgetting serious quarrels or disagreements that may have occurred early in marriage. Ever heard the saying that ``If you make it through the first year the rest is easy?`` This is true of this couple. The secretive nature of Cancer has the potential of clashing with the openness of Aries. Aries can be moody too, but not quite like her. What happens when two moody people live together? It`s either chaos or balance. For example, if Aries is in a great mood but Cancer is not, Aries may try to ``cheer her up`` and thus create a balance. Of course, this could be reversed, making it 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, she may back away from situations, which have been hurtful in the past.
