This is what psychopaths do.
They lie, and then they try to turn things around to make themselves the victim.
They only care about themselves.
That's the game they play.
If you call their bluff, they get angry at you.
They are the ones telling the big lie, but if they get busted they lash out at their accuser.
They make excuses. They won't repent. It is not their nature to repent and come clean.
They will always attack the people who call out their lies.
So what's to be done?
