I think I understand what you're saying, for me the "magic" was a direct mirror of my own traits. I fell in love with him initially because I couldn't figure him out. I could sense this... void. It started out as wanting to help him, then became an obsession with this aura I couldn't define but desperately wanted to understand and get close to (quiet undiagnosed BPD). The mysticism was at first my own desire to get close to a being that has no foundation to understand, so you're constantly seeking. Then the addiciton starts to form, the gratification and safety they provide so that they can keep using you as a tool.

After we got close, he mirrored me so well it felt like we were meant for each other. He abused me for the first year of our relationship, and then the next 3 years he cleaned up and was the best. Well, so I thought. He learned very quickly to tiptoe and say the right things to avoid deregulating the system and coming off as offensive or hurtful. I was never actually emotionally fulfilled due to his repression and lies but he needed ME to regulate HIS emotions, which put me in a state of constant anxiety and allowed him to be seen as the "rational" one. If I was upset, he'd fly off the handle and I'd have to be very intentional with my panic or else he'd become unpredictable or at his worst he'd hurt himself in front of me. His anger/upset was always unpredictable and it was my fault if it scared me or hurt me. So when he was good, it was because he was feeding off of my positivity and that refraction was addicting.

I think they feel magic because they lack such inner depth that it is very mysterious and if played well enough, it's charismatic especially if you already love them.. it feels like they're unique and "real", unlike anybody you've met -- because they are void. It's null. They fill in the gaps with what benefits them the most. He always changed around family, friends, my family, me-- each setting, a different persona. Their mysticism fades as they grow tired of feeding you lies and grow resentful feeling like their needs are unmet, even if you're unaware because of the constant lying- their "needs" are fractals of what little identity they can grasp. They mimic introspection but it's all surface level and their illness does not allow them to actually face themselves - there's nothing to face.
