This combination is usually hard to match. Cancerians, ruled by the moon, are moody, sentimental and secretive. They never really come out of their past. That is why you would often find that Cancerians are not the ones to easily forgive or forget serious quarrels that may have occurred early in their relationships. This relationship will have initial hiccups but if the two can sail through the first year or so, the relationship would then proceed smoothly. The secretive nature of Cancer has the potential of clashing with the straightforwardness and openness of Aries. Moodiness of an Arien is never as bad as that of Cancer. This could either create a total chaos or the two can work out a balance. Chances are that they will be able to balance one another. What may be of little concern to an Arien, may prove to be a very traumatic or even devastating shock to Cancer. Though the Cancerian holds on with the tendencies of a crab, he has a tendency to back away from situations, which may have been painful in the past.
