THE FEELING OF JEALOUSY (IN RELATIONSHIPS)

As listed in the Oxford Dictionary, Jealousy is: 
          "Feeling angry or unhappy because someone you like or love is showing interest in someone else."​

The Editor’s Example of Jealousy: 
Harry and his wife Ellie attended a neighborhood party together. As the evening passed, Ellie was suddenly missing. Harry asked the host if he had seen his wife, Ellie, and the host replied, "No. Should I ask the DJ to page her?” 
Harry said, "No, don't bother, I will simply approach that beautiful blonde woman, with the slinky black dress who is standing near the bar and start talking to her. 
The host said, "How will that help you find your wife?" 
Harry replied, "Because as soon as I talk to another woman, she always immediately shows up!"
