There are reasonable number of people in western countries married to ex WGs, prossies. Some are happily married, some are due to other motives.
I do not know whether this is relevant or not. But I have read the stories where Americans, British, and other western countries married with ex WGs, prossies from Thailand’s and other south East Asian developing countries.
Young ex WGs, prossies girls coming from poor background are attracted marrying the guys same age with her father due the attractiveness of living, working and then settled in the western countries. This stories is not new.
Similarly to beach boys (e.g. cowboys, male prostitutes) in Caribbean, south East Asia marrying an old widow similar age with his mum for the same motive.
