Thanks for this very interesting read. The Ex seems to fit very well too.
I like to read about psychology and I add this to the Red Flag list so I do not end up with "that type" ever again.
My stepmom is one too and whatever you say, she has already done it, and it was better. How boring. Ultimately those superiority traits are the ones that prevent them from seeking help while their lies just keep getting bigger and bigger, and the efforts to cover for them too, as well.
Until disaster strikes...
How very sad.
