How do you deal with

They either have no self awareness or they're a manipulative sociopath.

Study up on how to spot a sociopath (I can help you with that).

If you conclude that this person is a sociopath: work on detaching yourself from them and getting away. I know it's really hard and it will take awhile.

If you conclude that they're not a sociopath: work on your communication skills. I know, they're the one with the problem. But by improving yourself, you'll influence them to improve, too.

I'm rooting for the Special Prosecutor.

I have met this, and it makes it very difficult to get through to them. There is a mental barrier that prevents them from understanding their faults.

Let em. If they're right the truth will eventually sink in and I have work to do on myself. If not, their mistakes aren't my problem.

well my wife got my attention by leaving me
when it was the first one I blamed she had changed and she was the problem ,
when my second wife left who I adored ,I got the message loud and clear
I was the problem

Have 0 expectation from them.......Ignore them if you can.

Vote them out.

Oh ,no ...nah uhh ...no they don't ... no one is perfect .. it's important to take responsibility for our own actions

Shoot them.

walk away, then run

Always two sides to the story. Most will blame others. Take responsibility for ourselves.

Ignore them and move on
