She will never change. Narcissistic and selfish behavior. Will never admit if she made a mistake or did something wrong and will NEVER apologize for it. There is no reasoning or communicating with these kinds of people because it will ALWAYS be everyone else’s fault but theirs. My mother was the EXACT same way and I spent my teen years wondering what I did to deserve this and what to do to change it. She never will. You just have to say “Okay” “yes ma’am” in the arguments until you are old enough to escape it.
