Welcome to the boards!
This may not apply as much in your situation, however, for me what has been key is to focus on working on me and not only working on me but working on me FOR me. Not working on me to change her. Even when you think you might be working on you for you, there could be a subconscious expectation that she will change if you change. You have to look at everything very carefully as you move for. Keep posting more here as there is a great amount of support as you move forward in your relationship. By all means, don't feel like you need to just leave her because of the possibility that she may have a PD. Having a PD is not a death sentence for a relationship and if both partners are willing to work together, you can have a great relationship so hang in there and continue to learn as much as you can.

Hi Help_WiC,
Thanks
Woodchuck for sharing these very helpful comments! Yes,
Help, you are lucky to have a partner who is self-aware and interested in reading up on this. I can imagine it is quite a shock for her... .for some extra background on how this topic typically goes see here:
Telling Someone You Think They Have BPDHow To Get a Loved One Into TherapyThere is a lot to learn, but do not give up hope. Working on communication can make a difference. I taught my SO some validation skills and it made a big difference for both of us, me getting to hear him respond to my feelings, and him having the words ready when he really couldn't think of them on his own. He was really grateful for this help, and it cut down on a lot of hurt feelings.
wishing you peace, pearl.
