wanting something that others have isn't envy, that is covetousness.
Envy has always an outward focus; we desire some item, person, or attribute possessed by someone else, and we are discontent or resentful about not having it. And often the person who is envious, hurt the target of their envy.
Jealousy on the otherhand has an inward focus, for example; the protection of one’s own items or relationships, especially romantic relationships. You can envy someone else for his girlfriend, but someone flirting with your own girlfriend makes you jealous, not envious.
The difference between envy and jealousy is that, in certain circumstances, jealousy can be a positive thing. Envy is never presented as positive. The type of jealousy defined as “zealous vigilance” is the unhappy or angry feeling caused when what rightfully belongs to us is being threatened.
