Mule,

We are here to listen to you and support you emotionally.
SWOE is an excellent book to understand if your pwBPD is a borderline, narcissist or both as it has an excellent assessment tool in the third edition.
I personally feel that the tools in the book have less teeth than another book you may want to look at "Stop Caretaking the Borderline Or Narcissist: How to End the Drama and Get on with Life" by Margalis Fjelstad.
There are also resources on this site to look at as well at:
https://bpdfamily.com/message_board/index.php?topic=329744.0You can vent here, ask questions, as there are many people here who have the same or very similar story to yours.
Be sure to take self-care as this can be exhausting, whatever that may look like for you.
Take care.
