It sounds like its been a really tough week for you. It's not fair, it's painful. But it will get better. Some days will be worse, but the overall trend will get better.
My only advice is when your W goes on a rant and you can't validate, and she's blaming you for everything wrong in her life, you don't have to listen. Just leave.
Take care of your self.
