I am looking for a scientific resource, preferably a book with non-academic focus, which covers these topics:

- The dynamics of BPD female and NPD/caregiver male. How did the NPD/caregiver develop his personality? What to do if I'm a caregiver?
- The dynamics of BPD female and her lesbian partner
- **How does she interpret love?** What does she think/feel when she's manipulating both boyfriends with consciousness, and laughing when her friends asked?

I've just finished *Stop Walking on Eggshell*, and I feel that it does not explain the above questions. GettinBetter does cover it, but it has low reputation on being scientific.
