I need advice

so SP and I have known each other since April and we started off with liking each other, but we had a disagreement which causes to not talk for about a a month. About a month after this disagreement, we had had a really deep conversation and we had started talking romantically now after talking romantically for about two weeks I made a very impulsive and bad decision decision to cut him off. Since then, we’ve had a couple of talks, but it always ended with us arguing. Fast-forward to now I miss him a lot, but he literally wants nothing to do with me because of the arguments that we have had, and he feels like he’s at peace and I would disrupt his peace. I’ve tried many ways to tell him that I won’t and that I want to try again, but he’s not budging. A few nights ago I ended up doing the 369 method and I haven’t really had any results yet. I figured I’d try this method because it’s worked for me in the past on people, but I don’t know if it’s my doubts about the situation or what. he claims nothing to do with me and just wondering what everyone thinks I should do to manifest him back. I’ve tried affirming. I’m just not good at keeping up with it. but like some really really good methods that work even when you’re in doubt? Thank you and all advice is appreciated.
