Hi hunterrose,
I'd like to welcome you to bpdfamily. I'm sorry to hear that. It's frustrating and it feels hopeless when everything that we try to do w/ a pwBPD doesn't work. There's a reason why your wife acts the way that she acts. First, I want to tell you about a conversation that I had with my son's mental health therapist. I take him to his appointment every second week, he has a learning disability and he's a HSP ( highly, sensitive, person)
We were talking about validation and let's say that you planned to go to an auditorium for a family outing and you get there and it's closed. You forgot that it was closed on a holiday and it's not a big deal, you can just find something else to do. Your daughter later on has a tantrum, it's because she was really looking forward to going to the auditorium but she doesn't really comprehend that it was closed and that life is flexible, you can just plan something else. That tantrum may of been preventable if your D's feelings were validated. Her feelings of disappointment were getting worked up throughout the day and it came out later on.
That being said, a pwBPD need a lot of validation, the person feels low self worth, have low self esteem, self loath and are hyper critical towards themselves and others. You can the lessons to the right side of the board, you can find validatiOn in lesson 3.
