I had more done to my ex. I have a friend that has been into wiccan for years. She did a karma spell on him to return his negativity, karma, etc to him.
The candle was a 12 hour candle that burned in 20-30 minutes when she did. So, very quickly. Meaning he had generated a lot of bad karma my way. She was convinced all the bad things happening to me was because of him. Very clearly, "it is him".
Of course, people can say the candle might of burned that quickly due to some faulty makeup or air quality.
