SOMEONE WHO TRIES TO MAKE YOU JEALOUS HAS INSECURITY ISSUES
If someone tries to make you jealous on purpose it is the closest act to hatred and the person may even be a possible narcissist. I say a possible narcissist because they want your attention only for reassurance. But, the main reason a person tries to make you jealous is wanting power. It is about strictly wanting the upper hand over you to make you feel "lower" or less privileged. It can be because they are seeing that you are accomplishing goals or gaining more in life or just a generally happy person. So, it is about their own inner conflict and the other psychology is that it is about "status". The person wants to feel respected and assertive, but it is an obvious act of their own fears and insecurities. If you are experiencing feelings of jealousy yourself, it is time to face yourself by working on your self-esteem. If you are around people who are jealous because of their own insecurities, let them go for good or until they have done the work to change. The sad truth is that some people don't want to change. So, in most situations, it is best to let them go for your own well-being.
