My brothers wife. I am sure she suffers from BPD. Last night she pulled the old oh ya your brother can join us for thanksgiving trick. Predictibly, she removed that invitation this morning. She has been giving my brother a hard time. I see his mental state detoriorating. I spent 10 years of my life in a relationship with my ex who has BPD. This is not my first rodeo. I veiw her actions against my brother as an actual attack of violence, because of the effect it has on him. I am getting ready to turn her mind into a puddle of vomit as an act of self defense. Can some one please tell me the reasons why I need to be compasionate in this moment and not do this?
