What were the effects of the spell?May be I can add to this from the point of view of the jealous person, I didn't feel fear, I felt anger, my jealousy always comes from a deep hatred of the object that is causing my jealousy.
I suffered extreme jealousy with a Dom, to the point of casting a spell on him. This had nothing to do with fear of losing him but I despised the other sub. I compared myself to her and was angry that he could even consider being with her instead of me, It made me feel bad because in my warped mind, it was saying that I was uglier than her.
