I felt that too… and I completely understand and empathize with you. The deep, soul-connecting bond that convinced you without a doubt, this HAS TO be your person or no one at all.
When connections like that are made between two healthy people, then yes, an emotional bond most likely has been established… this is what throws you into a confused frenzy. We “project” our own emotional capacity onto the narcissist… but they don’t have the proper wiring to function like we do.
Narcissists are UNABLE to form emotional bonds. It’s their pathology. They are, however, masters of mirroring. They observe your emotions and reactions and reflect them right back to you. This makes it appear as though there is a solid mutual bond between you and the narc. It’s totally superficial, one-sided (you bonding with them only), fleeting (their egos must be constantly fed), and nothing genuine about it.
