An obvious telltale sign of BPD is dividing the world into black-and-white extremes. Either a person or thing is 100% perfect and angelic, or 100% evil and demonic.
As for Chinese being superior to Filipinos? In general urban Chinese are more financially successfully than rural Filipinos. But you have to look at their hearts too. Dianne may not be at the top of your perceived hierarchy just as she wouldn't be at the top of American society like a Hollywood star, but she's got a much better heart than Lisa. And Dianne is infinitely more loyal to you than Lisa was. Plus she's definitely above average in terms of looks and intelligence for a working-class Filipina. I am certain that she is better-looking and more intelligent than many Mainland Chinese women.
If I were you, I would pick simpler Filipinas like Dianne over the more complicated Mainland Chinese women like Lisa. It feels good at first to have a bimbo trophy girlfriend, but when reality strikes you will regret it. Urban Chinese might be more suitable for some guys, but for guys like you and me, the more traditional Filipina is better. Even Rock says that Filipinas can have such authentic, loyal hearts. On the other hand, Mainland Chinese can be shockingly cold and mean, both at first sight and after you get to know them well.
The average Mainland Chinese has much less conscience and empathy for fellow human beings than the average Filipino does. Traditional Catholic society in the Philippines is a completely opposite universe away from the ruthless, heartless atheist Communist society of China. China is a very low-trust society, while Filipinos are much more amicable and trusting. Plus, due to the one-child policy and rampant money worshiping in China, dysfunctional families and relationships are now everywhere in China. Filipino families remain much more traditional and functional.
My bottom conclusion is that Dianne is better for you. You've got nothing to lose by being with her. You have already experienced the pleasures and horrors of dating Mainland Chinese women. Your dad once even warned you that he's worried Chinese women might break your heart. Well Lisa just did. You've attained a Chinese girlfriend and experienced what it's like to have a relationship with them, and you should be satisfied with that. Now my opinion is that going back to be with Dianne and Angelo would be the most rational thing to do now. Why?
Because Angelo and Dianne truly love you, and really miss you. But Lisa does not. Many of those "hot" Chinese women you talked to had such cold, sinister vibes. I could just sense that right away when we were talking to them, but you were mesmerized by their superficial looks, and their mean, cynical words just flew by your ears. Dianne would never say the nasty things that the Guangxi lady told us.
You've been there, done that with Chinese women. You've had great Russian and Chinese adventures. Congratulations, you've ticked this off your list of "things to do in life" and won't regret it. Now you should go back to being a family man with your family in the Philippines. You may not have much passion now, but passion and love are things that you can learn to grow and cultivate. In the long run, you won't regret it if you go back to being with Dianne and cultivate a loving life together with them.
