How to know when to stop sending curses towards someone?

I have programmed all of my curses so that they only cause harm that is exactly equal to the harm this abuser has caused me… Which should still cause them many, many months of agony.

I felt instant relief after the first curse (which was a layered attack). I then did a second one petitioning a demon to help with the curse if necessary. I also told this demon I would reward them once they show me a huge sign that the curse has worked, since there’s not really a way for me to know otherwise.

I haven’t received a sign yet, but I have noticed that this person has done certain things with their phone settings to make it look like they’ve blocked me when they actually haven’t. I noticed they made these settings literally the day after we stopped talking (before I did any curses), and the settings have stayed the same for over one month. I tested it with a new phone number when I was overseas and can confirm they’ve made these settings intentionally, and there’s really no other reason why this person would do that other than they want to receive any msgs I send them while making me think that I’m blocked and that they aren’t receiving them (I haven’t sent them any msgs in over a month btw and don’t intend to ever talk to them again).

I don’t have much lingering resentment at all after these two curses, and I’ve barely thought about this person in weeks which has been a huge relief. However, occasionally, I will have an awful memory cross my mind, and for a moment I’m filled with rage and hurt again. The frequency this happens has gotten lesser and lesser, but whenever I have these moments, I keep getting this urge to throw in another curse so that I can transmute this lingering negative energy while reflecting it all back to the sender.

I’m not really sure if it’s worth it though. I feel better 95% of the time. But I do not like the thought of this person not getting exactly what they deserve. I’ve heard of people using divination to determine how their curses are tracking, the issue is I am bad at trusting myself when it comes to interpreting divination results. Also note I am currently travelling for a while so do not have access to my tarot/oracle cards and would prefer not to light candles in a hotel room. If there are any suggestions for divination methods given these circumstances I’d also like to hear them.

BTW please don’t suggest a healing ritual because I have done many healing and cord cutting rituals. I’ve learnt that for me, proper healing takes place once I’ve restored an equilibrium between myself and the perpetrator via justice.

Thanks.
