Hi Rondy

You came to the right place. From what you have written, it seems clear you will get good ideas and support here if you continue to read and post.
But I can't seem to relate, and it is getting worse before it gets better.
My question is - am i the one whos off here - or is this BPD? How do i 'validate' her feelings? I've been 'withstanding' this for a while, so I dont mind the behavior, because I do love her. But I need help to understand.
The short answer is both. Its very common for the Non-BPD person to make things worse by how we react to the person with BPD. Many of us here on the Improving board find that we have been contributing to the problem. We can actually make the relationship a lot easier by changing ourselves. My relationship that brought me to this board has greatly improved since I found this place and started learning about the disorder, started practicing the tools but more importantly started focusing on myself. That means two things: Looking after and taking care of myself but also being honest with myself about my own emotional life and how I react.
I suggest you start by reading the tools over here to the right

and spend some time reading other peoples posts. There are some good articles on validation, it helps to ask specific questions or give a more detailed picture.
Can you give me an example, maybe a conversation that was difficult and you think you could have validated but didnt know how?
Im really glad you took this step. There is a lot to learn but you are not alone and we have a great community here thats committed to supporting and learning from each other.
