A lot of communication is needed to make this relationship worthwhile. Capricorn is too ambitious, practical and rational for Cancer, who's mostly driven by emotions and sees comfort of home and close friends as the ultimate happiness. Capricorn might also be a family person, but apart from that also enjoys meeting new people and socializing. Cancer's jealousy may seem inadequate to faithful Capricorn and Capricorn's contented and unemotional nature may leave Cancer wondering if the former even cares. The match is actually not too bad, but requires a lot of communication.
