This can be a difficult combination unless other elements in their natal zodiacs are more compatible. Aries will probably find Cancer clingy and oversensitive, while Cancer finds Aries blunt and hurtful. Both signs are quick to anger, so there could be fireworks. However, they are both forgiving by nature as well, so there is the potential to recover after conflicts. On the other hand, Cancers may forgive, but they have trouble forgetting past hurts, so issues may resurface in future fights.
Cancer craves closeness, stability, and intimacy. Aries is more independent and prefers to engage with a broader social circle rather than being part of an isolated twosome. Typical Cancers enjoy home-based or nature-based activities and cozy gatherings of friends, whereas the typical Aries likes to get out and mingle. Differing interests and lifestyle preferences may pull these two apart.
Another problem with the Aries-Cancer match is that although Arians tend to be generous and altruistic with their time, energy, and money, they can be emotionally selfish, which Cancer may misinterpret as coldness or indifference. Cancer, by contrast, has a tendency toward emotional generosity that in the extreme can tip over into a resentful martyr complex, which Aries will find aggravating and oppressive. This problem is exacerbated by the Cancer tendency to nag (Aries are quick to flee relationships when a partner assumes a bossy parental role).
Cancers need security in their relationships and gentle handling by their partners, and they enjoy spending plenty of time alone with their significant others, whereas Aries thrive on challenge, novelty, and excitement, and they do best in relationships where each individual is free to pursue some outside interests and friendships. Neither Aries nor Cancer takes criticism well, and both are cardinal signs, which makes them argumentative by nature. The success of this relationship will depend on Aries’ willingness to exercise verbal restraint and provide reassurance as required, and Cancer’s ability to toughen up emotionally and allow Aries more freedom and independence.
In a worst-case scenario, needs and preferences will clash irreconcilably, with verbally impulsive Aries blurting cruelties in the heat of battle and triggering a defensive or passive-aggressive response in Cancer. In a best-case scenario, Cancer will provide nurturance and stability for Aries and Aries will help Cancer become more optimistic.
If these two can manage to get along, they can also be good business partners because Aries entrepreneurialism and Cancer business sense are a winning combination. This pair can come up with great ideas together, after which Aries can promote the business while Cancer handles its day-to-day operations and practical aspects.
Note: There is more to astrological compatibility than sun signs alone. Other elements in a person’s natal zodiac also play a role. Ascendants (rising signs), moon signs, and other planetary placements and aspects also shape personality and affect compatibility. For example, a Capricorn with Leo rising will be more extroverted than a typical Capricorn, and a Taurus with Aries rising or the moon in Sagittarius will be more compatible with Sagittarius than a typical Taurus.
