So, if you ignore her, what is she going to do to “escalate”? Email you again? Glare at you some more? Text you? What’s the worst case scenario if you stop feeding her?
OP I'm not the poster with the aunt/uncle who want to be grandparents or the general pushy people. I have posted her several times about her over the past year, I don't want to repeat all of it but she wants access to our kids, especially my daughter. She doesn't hear no when either DH, myself or the kids say no to her. She will go behind our backs to try to pressure the kids when we say no. We've had to block her from the kids devices. It was just going on and on with her so we started using the gray rock techniques. I don't think they are working because she really doesn't care about access to DH or I, she wants my kids and to feed her fantasy about being whatever with my daughter. This is not going to happen.
I think that either my MIL or SIL has said something to her to get to back off from us. They are awesome but since she is a narc this may have set her off again. There were several weird paragraphs on her crazy email about me trying to break up her family unit and smearing her. My SIL who has had similar problems with her but lives farther away is the only person I have talked to her about her craziness. She may also just be imagining things in her head which is even scarier.
If her only escalation is more crazy emails, glaring at me, bad mouthing me to other relatives then I am fine. I don't care and we'll just continue to ignore it. What is freaking me out is her level of rage and not knowing what else she will do. She has been vindictive with some of her neighbors and damaged their property before but I don't see her doing that here. I certainly didn't expect her to chase me around at an elderly relative's party.
