Cancer: Territorial & Manipulative, With A Tendency To Close Off 

Among all of the zodiac signs, Cancers are the most protective. They have a tendency to be overly attached to the people they care about, often to the point where they demand to keep them all to themselves. Unhealthy ties to others might develop in Cancers as a result of emotional insecurity.

Even if they are no longer in a relationship with the person, they have strong feelings for, seeing them show even the slightest amount of attention to someone else can easily make this sign jealous. Cancers occasionally treat their loved ones as their possessions and want an amount of exclusivity that is excessive and exhausting to the other person.

Another issue with Cancers is that they frequently distance themselves from those who are closest to them. This defense mechanism of keeping to themselves is harmful and will only keep them alone.
