I met one, 30-something, quite attractive, well off. I'm not dating her.
Her job in Thailand doesnt pay much, but she was married to a guy in UK and lived there for 10 years and had a business.
But even though she's well off, I'm not sure she wouldn't need a man's money as she is raising her child on her own.
Another one I met worked in Singapore. Some of them work outside thailand for higher pay and then come back.
