In many ways the two of you are opposites. CANCER needs a lot of domestic and family activities. Nurturing others and personal involvement with others is a necessary part of life for CANCER. Family and close friends are extremely important for CANCER, while CAPRICORN often becomes emotionally detached from personal affairs and may fail to fully appreciate CANCER's more personal, emotional responses to situations. CAPRICORN may seem dry and perhaps overly ambitious to CANCER.
Your differences can serve to complement each other only if you really understand and appreciate each other. Both of you do seek security, consistency, and fidelity in relationships, so there is a reasonably good chance that over time you will develop a greater appreciation for each other's opposite qualities.
