How to decline meeting a confirmed flying monkey without triggering them?

I have an aunt who’s Nmom’s sister. She has told Nmom about what I’m up to, constantly belittling everything I said when I used to talk to her.

I go grey rock and VLC, saying nothing I do. I block her and all flying monkeys on social media so they can’t know what I’m really doing (which is being normal, happy and safe, which they’ll try to destroy).

Today she’s reached out and suggested to call, how to say no without the drama? My life is good now and no way I’m letting her back in it. She usually throws a fit of abandonment wounds at me when I decline.

My thoughts are just to say something like:“maybe someday, I want alone time this weekend.”

What do you think?
