i know of a situation where i wish a person would go NC with son/DIL. they abuse her, shout, undermine, shame her re disability, demand that she not waste money on careworker, throw out her furniture, pressure her to sign house over to them, and get her to pay their energy bill. and more.
but she will never stand up to them. almost colludes in being abused. frustrating and disturbing to hear about/witness.
she makes excuses for them. minimises what they do. while suffering from it. almost at times says she herself is in the wrong. i have had to step away from trying to support her. it was driving me mad.
