Anyone have any experience with anything like this?
I think we all have, in one way or another. It's the "let me use and don't make waves or I shall blame you for everything and make your life miserable" train of thought.
The good news is..in a weird kind of way...he is already using...he is already blaming...and your life is already miserable, so there is really no wind in his sails.
Because they "say" something, doesn't mean it's true. More likely it is distorted, self-serving, and all about them and what "they" want, with no regard for anyone else.
It's called the crazy train, and sweetie, it may be time to check the next stop and prepare to exit. It ends when you say it ends.
Hugs out to you because I know this is painful.
