You clearly know little about females in Bangkok/Thailand. In professional positions such as accounting, legal, donors, banks, airlines, etc.....etc, as well as entrepeneurs there are thousands and thousands and more females who are fluent or almost in English. These women are attractive, smart, well travelled internationally, etc and a high % are unmarried and never have been. I know because since the mid 1990s until I retired from working in Thailand I employed many females, as well as working with females in sub-contrac tors, lawyers, etc.
Go to eat in any office building at lunchtime in Bangkok and females outnumber males. Genuine and many attractive females and I guess a high % are unmarried, don't have a partner, maybe never have.
