To keep things short; a long time friend and i had feelings from the start despite the age difference, awhile after he had come of age we started to cross that line and soon after it became toxic so we decided to stop and remain friends, however since moving on ive had to entirely cut ties because of his jealousy and sense of possession or ownership over me. For that reason Im not sure if something more serious than a cutting ties/cord cutting ritual, especially after my brother, also being his friend, had him over and he, despite my brother pleading him not to so they could still hang out, put a note under my door saying how he missed and loved me. Nothing in his situation has changed, Id be walking back into toxicity if I went back, and I need it clear to him and the universe that i stand by all my statements that I want nothing to do with him as long as its only going to bring me negativity. What are your options/thoughts/feelings/etc? Any and all insight is much appreciated.
Through mundane routes, seeing as he is himself favorable towards notes perhaps write one back to him. It seems like you already have the perfect words to put down too;
"Nothing in his situation has changed, Id be walking back into toxicity if I went back, and I need it clear to him(you) and the universe that I stand by all my statements that I want nothing to do with him(you) as long as its only going to bring me negativity."
That statement seems pretty short and sweet, and decisively rigid. Make two copies, one for yourself and one for him. Sign both, date both, keep one for personal records, and make sure that you have at least one other person you know present to witness you handing it to him. Have that person sign, date, and also write the time of hand-over onto your copy.
It sounds excessive, but planning ahead is very important. Always hope for the best, but be prepared for the worst.
If he continues to chase after you in a way that is unwanted for more than a month (keep everything he does written down, dated, and signed... never throw anything away) or if he escalates his attempts even a little bit, do the same process as above with a new note, specifically stating you will make a report to police if he does not immediately stop.
Most vital thing: Follow through. Police will not likely do much at first, especially if there is no threat of violence. But it will generate a case file, and a report number. Get and document that report number.
If he continues still or escalates, report and document again. The idea is not ecessarily to get a police response but specifically to have a legally documented series of events. In all likelihood, he will give up on his own after a while. A good 90% of the time people will move on. But if it does happen that you are made uncomfortable or afraid, or if he threatens harm to yourself -or- himself, you have solid ammunition for an order of restraint. At which point he will be legally obligated to stay away. Continue the record and report from there.
As for the spiritual, a cord cutting would definitely be worthwhile. Separate yourself from him emotionally, spiritually, and karmically (I think that's a word.... Well is is now!). Having a physical action of cutting ties does go a long ways for people. Don't forget that after you cut the representations for you and him apart from eachother, place yours at an elevated spot in your room where you can see it. And physically put his representation out of the home, either in the trash or literally drop-kicking him out to the curb.
An additional option would be to also use whatever object (poppit/doll/effigy/symbol) you have to represent him as the focal point for a lesser banishing. Or some other form of banishment you are familiar with before removing it/him from your home. Sort of a "get out" and "stay out" one-two punch.
