I'm sorry to hear you had a bad experience with a "Farang". It's sad because many westerner come to Thailand for a few months and meet Thai girl, she fall in love and he leave and promise to return, but never do. I'm staying Thailand for the rest of my life. I'm financially secure for the next 135 years. I don't think I'll live that long. I really would like to fall in love again, but right now I'm still learning about Thai culture, Thai language and of course Thai women. I hope someday i can meet a wonderful Thai women like you that lives in or near Chiangmai.
Sincerely, Thomas
