In addition, here is my experience...
Although it has just been 3 days after I have cast this spell for someone to think of me --- something I have casted on the same person 3 years ago and have recasted just recently.
I felt there was something wrong immediately after I have casted that spell as it seemed to have backfired on me as I have been the one thinking about the person constantly. However, I have casted this realization spell early on today --- and for some reason I don't understand, it felt like everything is going to be okay. I don't understand it as although it hurts what this person has done to me --- I also at times felt at peace that everything was going to be fine. Does that make sense?
There's a lot going on here but it sounds to me like there's some force that's trying to tell you that it's not a good idea for this person to notice you but you've cast the spell so many times that the forces are clashing; my advice is to move on and get happy with yourself, there's no point trying to force an issue that doesn't want to happen because you get that kind of cross-chatter and it can be upsetting :/
Yes perhaps it is best to move on. Love isn't guaranteed no matter how strong the witch. Find love the natural way. What your feeling could be what they felt at first. Center yourself and let go of the past. The spell(s) should follow.
