I saw this interesting idea recently and found it intriguing:
PERSPECTIVE: Jealousy is simply and clearly the fear that one does not have value. Jealousy scans for evidence to prove the point - that others will be preferred and rewarded more than you. There is only one alternative - self-value. If you cannot love yourself, you will not believe that you are loved. You will always think it's a mistake or luck. Take your eyes off others and turn the scanner within. Find the seeds of your jealousy, clear the old voices and experiences. Put all the energy into building your personal and emotional security. Then you will be the one others envy, and you can remember the pain and reach out to them.
What is jealousy, exactly, and where in our psyches is it born? It seems that such a natural human emotion can’t be entirely unhealthy. Like anger and fear, it serves some purpose in our sense of well being, perhaps to warn us or to inspire us. And such a complex emotion can't be "simply and clearly" summed up or caused by any one aspect of our personality.
For a man, jealousy over a woman is usually first more related to sex than to anything emotional, but even men do feel jealous when a woman they care about gives her affection and attention and admiration to another man, even if she reserves the sex only for him.
Jealousy defined, first of all, I guess is the unpleasant feeling you experience when you perceive that someone is giving something to someone else that should be given to you. It’s a combination of confusion (that should be mine, why is it being given to someone else?), fear (does it mean that there won’t be enough for me? Am I about to lose something valuable?), pain (related to rejection, I guess, that someone does not consider me as special as I think I am), and anger (result of pain). So these emotions can occur in varying degrees and mixtures, and the whole combination, the jealousy, can occur in varying degrees. Like any other unpleasant emotion, its presence doesn’t necessarily indicate a problem, but the way you handle it can cause huge problems.
As an issue of low self-esteem, I see “envy” as what’s involved rather than jealousy. Perhaps it’s a subtle difference, but to envy someone is to strongly desire what they have—again, it can be a very unpleasant emotion but it doesn’t involve the same elements as jealousy. With envy, there’s no sense that the something the other person has should rightfully belong to you, no sense of confusion why they have it and you don’t, no sense of rejection really. Simply really wanting bad what it is that they have. As it relates to self-esteem, yes, I see envy as an indicator that one doesn’t feel deserving to have it. When we envy someone, we feel we have no choice, all we can do is watch and want. "Eat your heart out," the saying goes. Perhaps we don't feel worthy or capable of setting that as a goal for ourselves, nor do we feel any confidence that we could ever achieve it, so we just...want it.
With jealousy, one definitely feels deserving to have it, that’s the source of the emotion, that feeling that you are worthy of it, that you earned it or deserve it or have a right to it, but it’s being given to someone else. To me, that’s actually an indicator of good self-esteem. Maybe in extreme jealousy, it’s even an indication of too much self-esteem—ego, the feeling that you deserve everything from everybody and anything anyone gives to someone else makes you jealous because it should be yours. In this sort of person, there’s no feeling unworthy of having that thing, it’s just the opposite.
In the matter at hand, I can say I have a super cool life, I can’t complain, and I'm appreciative enough of what I've got, who I am and what I've done that I'm not likely to envy anybody else. If I see something I want, I either set it as a goal for myself or I examine what it is I want and why, and sometimes find that I don't really want it after all. Whatever I would like to have that I can’t have right now, I can quite easily put out of my mind (if I’m left alone and not provoked), or I can put it on the shelf of my heart labeled “Someday I Will Have This, Just Watch and See.” I feel no sense of being unworthy to have it.
And, dear Lord in Heaven, I absolutely never envied Her for what she has. I would sooner convert and become a nun than to step into her shoes. Consider for a moment what has been seen through my eyes. While the relationship may be the most perfect, fulfilling, inspiring, healthy relationship in the history of mankind, consider the small sliver of that relationship I have seen. Two people tossing romantic cliches back and forth to each other, making declarations of love and devotion that sound quite large and impressive but really have no substance when you look close, telling very little about them other than the fact that they both know how to use Google and how to find music on the internet. The slice of relationship I saw, it could have been any two people in love, very generic.
Come now. Do you not know me well enough to know that I would never envy this? Sure, everybody wants love but does this seem like thekind of love you'd expect me to eat myheart out for? (Again, it's very likely the relationship itself is very deep and earth-shakingly good, but I would only be able to envy what I could see, and what I saw was not something I want.) When have you ever known me to be impressed by a cliche?
You know me, I'd get a bigger kick out of subtlety and more flattered by something that seems very understated but is in fact something deeply meaningful to me or to us. I'd be more touched by a very simple gesture than week after week of grandiosity and hyperbole.
You can believe it, or choose not to believe it if your ego requires you to think certain things about my motivations, but if you sincerely think that my motivations were jealousy and envy, you don't know me well at all. Envy, or feelings of being unworthy, were never a factor here.
Jealousy was born when I began to perceive that certain things should be given to me, that I had earned them or that I was led to believe they might be given to me, only to have them yanked out from under my nose and given to someone else. Jealous--yep, I was.
I’m fortunate enough, though, to be emotionally very flexible. I’m pretty good at changing my perspective, developing healthier (and less painful) ways of seeing the world. In short time I no longer felt that what was being given to Her should be given to me. I felt betrayed by certain manipulations and deceptions, sure, but the jealousy part was easy to get over. Love is love, and you can’t fault someone forever for giving it to the person they feel it for. It’s life. It happens. We could have been friends, and that sting of jealousy would have stayed gone. Yes, really, gone. I no longer felt pain to see the lovers, nor any sense that I should have that. I was curious. I wanted to understand.

Of course, some people get an ego boost from inspiring jealousy in others. And certain well-placed words or actions can bring jealousy back from its cold green grave--that feeling of being entitled to have something which is being given to someone else, that feeling of rejection. When jealousy is gone, how do you get it back? You simply get the person to believe again that they should or could have what's there. Being once bitten, the person might be reluctant to believe it this time, so you might even have to go so far as to suggest that not only will you give her that thing she has earned and is worthy of, but that you will no longer give it to the other person at all. Bang, the person is now ready to feel jealous once again when it turns out to be untrue.
Most importantly, the jealousy could have been severely eased or even completely eliminated with just one brief, sensitive, direct conversation--or even just an email--in which you expressed regret at any pain caused but shared your honest intentions and shared some of the reasons things turned out the way they did.
But if inspiring jealousy was your goal, yep, you did it just the right way.
Imagine the hypocrisy of a man who intentionally provokes jealousy in a woman and then criticizes her for feeling it and questions her self esteem. Especially when his own jealous impulses have caused him to do things like this:
