Hello. I just found this site and am very excited to read and absorb all of this great information and support. I cannot believe it took me +5 years to just Google "how to tell someone they have borderline personality disorder".

I am posting because I need some help with a specific situation. I look forward to becoming a contributing member!
My mother has BPD but doesn't know it. She recently verbally attacked my wife and myself, telling us that her children (my sibling and myself) were happier than my children (one of which, who she was holding, was 7 days old at the time).
She later
almost apologized via email... .a big step for her!
I thanked her via email for her almost apology and told her I was excited to go on an upcoming vacation with her & my family and that I was hopeful an incident like what happened would never happen again (even though it happens nearly every time we see her).
She responded via email, saying that the incident was actually way harder on her than it was on us, because my wife spoke to her impolitely, triggering the incident, which she didn't. "I dearly hope that in the future (your wife) will be able to treat me with consideration and respect as I treat her and everyone I deal with." Thanks mom.
I now need to constructively and positively tell my mother that we will not be going on a vacation with them as a result of all of this. It would not be healthy for me or my family to be with them right now. I am using email because with spoken words, my mom re-writes what people say & how they say them.
I have been trying to figure out how detailed I should be, how direct I should be, how empathetic I should be. This will definitely rock her world and probably push her to demonize my wife even more so I want to be sure to get it right.
Thank you!
