Listen there are good and bad women and men in all countries. As English man I can tell you that forever in time many English women have been money motivated and beautiful younger women have dated and married ugly older guys who just happened to be rich. Is there any difference really between certain Thais and other nationality women??!! . Thailand is criticised for its prostitucion, like that doesnt exist in European countries !!!
I personally know a guy who has been dating a Thai women for 10 years and she is smart, intelligent and beautiful and probably spends more money on him than he does on her. She is a CEO of her own company , so you see its all about the quality of the person and their morals and needs.
