Honestly, I'm not sure why this thread has so many empty replies, but OP, you're circling something I had to learn the hard way and I don't think you're wrong to be suspicious of your own read here.
Your line about "the most dangerous beliefs are the ones that feel objective" — that's the thing that grabbed me. Because during my kundalini awakening, I was doing exactly what you're describing, just with a different symbol set. I'd get a physical sensation, a vision, whatever, and I'd go hunting through every text I could find until I found a framework that said "yes, this means you're on the right path." And the thing is, I was on a path. Just not necessarily the one I thought I was mapping.
Jung's concept of synchronicity gets abused in exactly this way. People treat meaningful coincidence as confirmation, but they skip the part where Jung himself was pretty clear that synchronicity isn't predictive — it's acausal. It describes a pattern, not a destination. When you see his Juno on your Descendant and feel that click of "this means something," you're having a synchronistic moment. But the meaning isn't baked into the chart. You're supplying it. Which you already know, I think — you're just not trusting that knowledge.
The Hierophant pull is what concerns me more, honestly. You mentioned the shadow side being rigidity, but I'd push further: in my experience, The Hierophant in a relationship spread when you're already questioning commitment can be a mirror of your own conditioning. Not "you should stay" or "you should go" — more like "look at what you've been taught a relationship is supposed to look like and ask who taught you that." My awakening blew apart every "supposed to" I'd absorbed, and the wreckage was ugly. But it was also the first time I could see the difference between a binding and a choosing.
Your instinct to burn the chart isn't destructive. It might be the most honest magical act you could do right now. Strip away the framework and see if you'd still be sitting there at 2am pulling asteroids. If yes, that's real. If no, you've got your answer — it was never about him.
