Dijmart, are we related? Sounds like my mother! Un-dx'd (nothing wrong with her thankyouverymuch!), but with obvious multiple issues. It was a long process, but I've had to pretty well cut her out of my life. (You might not to go that far of course, it's just what I had to do.) Enough problems as it is, you know? Moved thousands of miles away. Calls would come, visits about once a year. Each passing time I grew yet more distant and made it increasingly obvious I wasn't going to put up anymore with her b.s. or feign affection I did not feel. Her calls became less frequent. Visits (which were solely for the purpose of letting her visit her only grandchild) became completely unacceptable after my, "One week. Tops." prompted her to get plane tickets and call back to say she could "only" get tickets for a 3 week stay(!!!) Tickets not refundable. But of course... (I had to keep leaving the house or there would have been a homicide... )

On the phone, one time I cut her off abruptly with an exasperated, "Is there something I can DO about that?!" Only time it stopped her in her tracks. (Of course, it started right up again... ) I never call her and have not for years, with one exception. After getting divorced. Short, to the point, then "had to go".

I also totally recommend the "gotta go" (fake work, meeting, dinner, whatever) methods. Otherwise, she'd go on literally for hours. All by herself.

Never did much, but I did less and less of the talking over the years to the point of grunts and "huh"s. Like yours for not being able to get much in, but also because I was finally realizing that information was ammo. And I wasn't about to hand it over to her. (As you may have guessed, she does not know of my BP.)

Long and short, I personally found it easiest to do over a span of time, as she's totally thick in regards to such things. Eventually she got the message.
