Don’t do it. I messaged my undiagnosed, but I suspect bpd sister because I am worried about her and then her narc husband threatened to get a restraining order. Meanwhile they were the ones who treated me and my family horribly for months up until they were the ones who went no contact. I would get anxiety before going to their house and I didn’t piece it all together until after they went no contact. We did so much for her through the years, there is no end to their delusions. In a moment of weakness I reached out, only to get a slap in the face. Do not do it, these people’s delusions are honestly dangerous, take my advice and don’t do it.
