The moon is your sign's planetary ruler, but because you are born in the second Decan, or part, of the sign, you are also influenced by the planetary influence of Pluto. The sensitive and intuitive influence of the moon is partnered with the power and control driven influence of Pluto. It is this unique influence that allows you to be less emotional than Cancer's of the other two Decans. While the internal struggle may be severe, you often choose to let pragmatism overrule your emotions, which may explain for your secretive nature. You are much more open in loving, close relationships where your need for security is satisfied. Your planetary influence can cause a significant amount of jealousy to branch from your close relationships, so take care to avoid its damaging effects.
