There are 2 types of jealousy. The most correct definiton would be the feeling of being threatened by a rival in a romantic relationship or losing something of value to another person which happens to be yours already. This is what I consider the correct definiton.

The second is type of jealousy is more like Envy. Envy is a hatred/bitterness towards another person for having an advantage that YOU don't have. For instance, envious/jealous behavior such as a friend has a nice new car and instead of being truly happy for them you badmouth them or the car or make up something ridiculous because YOU can't afford it yourself. If someone has money and YOU don't you say they recieved it through less than stellar means. If someone is more talented than YOU you say their work isnt as good as anyone thinks or they are just lucky. This kind of 'jealousy' is destructive and displays itself as having a bad attitude towards the object of the envy and also being passive aggressive.
1. Cher was jealous when her relationship with her boyfriend was threatened.

2. Mike was jealous of her because he didn't have any nice things. He had no happiness so he didnt want her to have any either.

Being jealous is wanting to keep what you have and guarding it from other people. Being possessive. Not wanting others to touch your stuff.

Jealousy is very often confused with envy (the desire to be like someone else, or have their possessions), but they are not the same.

jealousy is when someone who is in love feels as if their girl/boyfriend is going to leave them or cheat on them.

jealousy is when someone in a relationship cheats on their partner and feels like there partner is going to rebel against them.
i love you so much that i wear my heart on my sleeve and i just want everything to be great. But i have a feeling that you are going to go back to your old ways and forget about me or find someone who is better than me, therefore i am jealous.

when someone dosent like another for no known reason other than not being like them. They wish they were like them so much that they start to hate themselves and tell people they hate the person they are jealous yet theres no real reason other than that person dosent think you're good enough. The jealous individual will do anything to see the one hes jealous of fall. For instance spread rumors, bully them, try to make it look like they are bigger than he is, etc.. at the same time they try to imitate you.
Michael was so jealous of him he went to incredible lengths to see him fall.

Not only is jealously is an act of greed, it's also being insecure in oneself.
Sarah is jealous of Brandy because she wants what Brandy has. Sarah will do anything to hurt Brandy because she doesn't like herself. So Sarah lives her miserable life in an illusion and never gets what she wants because she wastes her time looking at all the Brandy's in the world.
