I love this story, but one thing I will say is that I don't think asking someone again and again "do you have any negative feelings towards me at all" and refusing to take "no" for an answer, berating someone for hours over it until they finally say "ok fine yes I do" is healthy behaviour. It's almost CERTAINLY going to GIVE them negative feelings. Like whether or not your BF lied - you wouldn't have accepted him saying no. So eventually to make you stop asking, he told you what you wanted to hear. That may or may not have been the truth when you first asked him. And honestly I can see why he was frustrated and angry at the end of it.

That's not a healthy way to communicate.

Also, it's a mistake to think that the only kind of relationship is one where there are zero negative feelings. My partner and I feel negative feelings towards each other sometimes. Not malicious, but frustration, or hurt. Actually expressing our negative feelings (in a healthy way that isn't blaming or essentialist) is a healthy way to work through any misunderstandings and resolve the feelings.

But part of being in a relationship is trust. So if you ask someone you love a question, and they tell you an answer, to repeatedly ask the same question again and again shows you don't trust them and you think they are lying. And when someone knows you don't trust them, that's going to CREATE negative feelings in them, even if they didn't have the negative feelings before.

Just something to consider. The way you tell this story, I'm not saying he was in the right either, but you seem to think nothing you did had any negative effect on him, because YOU felt so full of love and light. You wouldn't stop talking "because of your Gemini moon sign". Maybe he had a rough day. Maybe he wanted some empathy from you. But instead you went on "for about an hour, with him visibly getting darker and darker". Do you ever think that this could be because he was feeling less and less heard? That he was feeling invalidated?

I understand you had a really beautiful experience and it was lifechanging for you and I'm so happy for you, but something that can happen to newly spiritually awakened people is "toxic positivity". Where they think that just telling someone "be positive" and "we can control our thoughts" is going to suddenly make them happy. You felt that you could "defeat" him and his "negative energy" by arguing your way out of it. By preaching zealously what in your mind the "key to happiness and the universe is".

But you can tell people these things and if they aren't ready, it will just be interpreted as invalidating. Just like YOU would have felt this way if some spiritual person had talked for hours to you when you're down about how moon signs and astrology prove that spirituality is real and all your feelings are under your control- before you had your own awakening.

You can't force someone else's awakening. You don't have to dim your light for them, but you also shouldn't blame them for not raising their vibration to your level, for being "negative". It doesn't make them bad people for being negative. It doesn't make them a narcissist either if they lose their temper after being constantly mistrusted, their word not being believed, and preached to about spirituality for several hours when they're feeling upset about something.
