jealousy comes in many forms, it may comes from people being jealous of you for your own achievements and ending up bewitching you for that. In the other hand it can come from the natural insecurities of your lover with suspicions and imaginations that you might be seeing someone. This one is very bad because your partner will not only start to seek some love spells to fix you, but he / she may hurt you one day, driven by the pain of jealousy. I stop such behaviors before they mature into fatality.
