You could always give them what they are jealous of... Or you could tell them all the ways they are better than you. Doesn't matter if the reasons are big or not, It'll make a difference.
if you envy someone you should have the set mind to work for it in order to pass said person and then people would envy you and it will be a continuous cycle until you die
jealousy...liking people for what you don't have....
Material wise??? get over it!! If you want something work for it! Study hard, study smart then get a job work for money and buy it.
that's just greed really
exactly
Relationship wise??? help the person overcome there insecurity.
If you feel threatened by a guy/girl making moves on your guy/girl reassure yourself that the both of you are together not them. Trust plays an important part but if there is clear evidence that your other half is untrustworthy or vulnerable in the particular situation think hard about where the relationship is heading.
Jealousy connected with relationship matters is usually derived from lack of attention and affection towards your other half or you. Make an effort, listen to what she has to say or try playing video games or watch a game with him. Its that simple no need to complicate.
