My wife was from Thailand. But I did not put much thought into culture differences. Thailand is a bit more like the USA than China is to the USA. For her, it was money and partying. She even once told me that if I gained 2 million dollars through my work she would have sex with me every day.

I am in agreement with Truegritter. There is nothing you can do about DJ. Making theories about what he is up to is a waste of time.

Your efforts in trying to coerce your W's thinking are futile right now. She will need to come to some sort of awakening on her own (possibly after an A with DJ) to realize the path she is choosing is wrong.
