During my time in Thailand, I witnessed many people become seduced with the country and its people. In particular, men often fell deeply in love and lust with the young Thai damsels. Women often fell for the Alpha Thais - the fit, happy Muay Thai fighters. Most of these relationships ended through some sort of manipulative and dramatic event, with the expat often complaining about "dishonest" and "deceptive" Thais who only see them as ATMs or sex toys. I lived this reality and mindset for most of my time there, even though I was never scammed by a woman, I bought into this victim mentality.
Here's my quick point: people will take advantage of weakness no matter where they are from. If you are weak and naive enough to try to buy someone's love through gifts and promises, that is your problem, not theirs. People, particularly women, will test your strength. If they find a weak spot in you that makes you vulnerable to others, she will not have confidence in you as a man. She could be Thai, white, blue, whatever.
This principle of strength is the same as it is in the classroom. Your students will not follow you if you try to pander to them through kindness. They will tolerate you and follow their own needs until the bell rings.
