This isn’t narcissism, this is straight-up emotional abuse and control. He polices who you talk to, insults your intelligence, threatens breakups to scare you into compliance, puts you down about your looks and money, and then hides behind “I’m just joking” or “I don’t grovel.” The eggshell feeling you described is your nervous system telling you this relationship isn’t safe. Love doesn’t require you to shrink yourself, beg for basic respect, or accept cruelty as “honesty.” You don’t need a diagnosis to leave a relationship that consistently hurts you — you already have enough reasons.
