Yeah, welcome to the family and thanks so much for sharing your story. It's so incredibly hard and I'm really glad you found us.
You ended your post with, "I need to talk." What specifically would you like to talk about? Ways to keep the drama to a minimum? Advice on therapy or a diagnosis? Whether you should stay in this relationship?
Side note, you posted on the "Bettering a Relationship" section of the site, so the advice others give has to focus on reconciliation. If that's not what you're looking for, report your own post to a moderator and ask them to move it to a different category (conflicted or detaching).
One thing I did pick up on was that you'd love for her to get a diagnosis, but unfortunately that's not a major help in itself. What really makes meaningful change is her wanting to get help and take control of her emotions. It's an uphill battle and it will be the hardest thing she's ever done in her life- most never do take it seriously. But there is hope.
Additionally, BPD is a mental illness of extreme emotions. When you're happy it's the best day ever! When you're sad it's like the entire world is against you in every possible way. There's rarely a middle-ground, even though that's exactly where our minds function the best. Your job as a partner is to be like a detective studying the clues- if she's down, make her laugh and tell her how much you love her. If she's angry, apologize for hurting her feelings and let her know how much she means to you.
This sounds so basic, so silly almost, that you might think you're already doing that stuff just fine. But I promise you're not, and it's not because you haven't tried. This particular mental illness needs positive confirmations constantly because they can become unstable over the smallest of things. It's like learning a new language in a way. If you're determined to make things work though, it's a language you must speak fluently to understand her subtle mood changes and what it may lead to if you don't take charge and help her find balance.
I hope that helps and please, ask away with questions!
