Aries's open, passionate nature appeals to Cancer, who often internalizes emotions and feelings.
Cancer can have intense, feminine energy and Aries can help them learn to release it.
Cancer can help Aries slow down and learn to be gentle, while Aries teaches Cancer to come out of their shells.
The Moon controls tides of the Earth, quietly affecting all life; similarly, Cancer works behind the scenes (while Aries rushes into battle).
Cancer tends to be sentimental and can teach Aries to slow down and appreciate life instead of always rushing on to the next thing. These two elements can be a great combination if they work together, using both emotion and action to get things done.
Aries is out there getting attention and Cancer is quietly supporting the back end.
Each partner's ability to provide what the other is lacking makes theirs an equal relationship.
Aries, on the other hand, may find the Cancerian sensitivity appealing; it's a good balance for the typical Aries bluntness.
Troubles may arise if Cancer's mood swings or Aries's aggression becomes hurtful.
However, Aries can help by reassuring their Cancer partner that they are loved and cherished.
Aries really needs to learn to listen to Cancer: the Crab operates on an instinctive level and their advice can help Aries avoid making silly mistakes caused by that typical Aries lack of planning.
Both Signs must take time to listen to their partner's needs and understand that they're coming from different directions to meet a common goal.
