Many folks do not know the difference between jealousy and envy. Envy is the desire to possess what someone else posseses such as heath, beauty or money which in and of itself is more benign than jealousy because it usually does not involve acting-out behaviors. In fact in some instances it motivates a person to improve themselves by choosing a healthier life style, a more lucrative job, or improving thenselves in some way.
On the other hand, jealousy is an emotional reaction to a threat of losing something or someone. For example jealousy often occurs in relationships yet is difficult to admit and also hard to talk about. In a study conducted by two psycholgoists at the University of South Carolina (Psychology Today, November/December 2016) it was reported that actions such as putting your arm around a spouse at a party or helping a partner's cute coworker draws a partner back in. Furthermore it was found that indivduals were more commited to the relationship after a partner took such mate-guarding actions. The researchers concluded a little jealousy can benefit a relationship while too much jealousy potentially has bad implicatons. Dealing with jealousy requires admitting to one's feelings rather than deliverying accusations--such as stating "I feel jealous when I see how others are attracted to and interact with you and I want you to talk to me the same way you talk to them." In addition couples need to assess what may be missing in their relationship and work toward incorporating new ways of being together.

Thanks for making the distinction between envy and jealousy. I think I've used the words interchangeably, but it's helpful in understanding my own behavior to keep this distinction in mind. I like your examples of how to speak about one's jealousy in a relationship, as it's all too easy to act out like a hot-head.
Your comment aptly points out how one can act out like a hot-head when jealousy isn't understood and addressed which may endanger a relationship.
