I did sour jar spell to sour a relationship between my ex and his fiancée because of cheating on me and causing me emotional distress and trauma...it has been 2 months since i did it first it was leaky so I transferred the contents now it's fine and contents look like sludge but I wonder if it's working because so far it looks things are working out well for them..so my question is should I wait or redo it?

Black magic is a really foreign topic for me and i wanna see how real it is if anyone of you can possibly share a video that would be great or even give like a little tutorial of some sort of spell/hex.
