Hi MistaNobody, I want to join UndauntedDad in welcoming you to the boards
It's great that you're reaching out for support
Here are a couple of links I feel are very important to read when we first arrive here, they have sure helped me:
Supporting your BPD partnerThe Do's and Don'ts for a BP relationshipI am not a therapist but I just ordered her some books online to hopefully help us both to better deal with things when they arise.
The first question that came to my mind was, has your partner asked you to order books to help
her better deal with things? A lot of what we do here is help ourselves to better deal. To focus on ourselves, our reactions to things and to gain perspective. It's a shift from placing the focus on our partners, to that of ourselves.
If your partner has not outright asked for these books, I might keep them under wraps to glean whatever information I could, for myself to have a better understanding of what the heck is going on.
We are the other half of the relationship and hooray, we are not helpless

There is hope for better days to come
It's good to have you here!
