This was one of my own mother's favorite tricks...like gaslighting...I always found it hard to actually say something (because I would then be called "hypersensitive" or some excuse) but I did finally just go no contact.

With others, I like to say something like "Why would you say such a thing to me?". "Do you have any idea how that makes me feel?" and "how can you expect me to just go on and act like you never said that?"

You are worth as much respect as anyone else.
