Very interesting story!
What is your experience with regular (non-hooker) women and educated college/university degree women over there?
Typical Asian women, take care of their man and in general don't want to wear the trousers in the relationship.
I've met a few exceptions. I employ 2 women who both wear the trousers in their respective relationships - one has a Phd and one a Masters, they are both extremely smart, switched on gals. Their hubbies are also very smart but no way they could tell those girls what to do. Most of the other women I employ are the subservient type and happy with it.
As a Westerner, you get to play a few leagues higher here than you could at home. Competition is pretty stiff out here and all Thai women know that men have lots of alternatives here.
At the end of the day though - what the bar girls want and the office girls want is the same thing. They want someone to take care of their parents when they get old. The only exception here is the rich who don't need that.
As a Westerner, don't expect the relationship to be 'cheaper' because the gal had a full time job. Paying up to care for her parents is the norm.
