I support you in your potentially life-saving resolve.
I lived in an Asian country and saw a lot of Western men get involved with what now in retrospect were clearly BPD relationships. A lot of it was dismissed as cultural.
Keep educating yourself and keep protecting your precious psyche.
My husband's ex is Asian. When he described the circumstances of their marriage, I asked how much of the problems were cultural and how much psychological/emotional. He said 50-50. I think it was more 70-80% BPD/NPD.
Some of the cultural values can be difficult to extract from the PD behaviors as Western families tend to function differently (status, face, acquisition and handling of property and assets, emphasis on parents and children).
