Sounds like my ex. Terrified to show vulnerability, since it was always horribly punished by the abuser, so they endlessly deflect blame onto others. And it’s not just a tactic, but an all-encompassing delusion that cannot be reasoned with and they don’t even see. And unfortunately, healing begins with being vulnerable, accepting responsibility, and trusting in others that want to help you.

(Not responsibility for why they are that way, but responsibility for how their actions hurt others and taking responsibility for healing, since no one else can do it for them.)
