In terms of relationships, Cancerians value security and loyalty. They tend to be family-oriented and prioritize their loved ones above all else. They are also known for their nurturing nature and are often drawn to careers in healthcare or social work.

On the flip side, Cancerians can be moody and prone to emotional outbursts. They may struggle with expressing their feelings and can often come across as passive-aggressive. They are also known to hold grudges and have a difficult time letting go of the past.

In terms of compatibility, Cancerians tend to get along well with other water signs such as Scorpio and Pisces. They also have a natural affinity for earth signs like Taurus and Virgo.
