Since I have gotten older, I am not the least bit shy of telling someone to back off. I have learned that if I allow people to walk on me they will!
I like BigSis answer. Don't answer the door. Even tell her face to face she's not welcome if you must. She's controlling because people allow her to be.
Has anyone ever put her in her place? When it comes to our own recovery, we do what we must to keep our sanity.
Take care teke. I hope you feel better soon.
Hugs
