Elemental chemistry

How you operate together
Both of you are initiators, so there is no shortage of drive or ambition. The catch is that two leaders can quietly tug over who sets the direction. Agreeing on whose call is whose keeps the power balanced.

Cancer & Capricorn in love & romance
Here is how each of you loves. Cancer loves deeply and builds a sense of home with their partner. They're devoted and affectionate, needing emotional security and reassurance — and they remember both kindnesses and slights. Capricorn is cautious in love but utterly committed once invested. Steady, loyal, and protective, they build relationships like everything else — to last — and show devotion through dependability. The chemistry works best when each of you names what you need out loud rather than expecting the other to simply know it.
Communication
Communication is where the water/earth difference shows most: Cancer reads the feeling under the words and Capricorn is practical and wants the point Slowing down to meet in the middle is the single biggest thing that helps.
The long-term outlook
Long term, this is a pairing with real staying power. The opposite-sign pull keeps things interesting for years. Keep investing in the parts that do not come automatically and it holds.
