One chap asked you about successful bar girl marriages. My advice is easy. Take to your toes straight away, the percentage of bar girl Farang marriages that last is very low and of those that do last for any length of time this is often because the Farang turns a blind eye to her indiscretions. Five years she has been a prostitute and still is, would you seriously consider someone like that in your own country as a wife?
You are tarring every girl with the same brush, which is not really fair. However, the percentage of successes is not too high in my opinion, but I don’t know of anyone reliable who is keeping the score. Entering into a bar girl relationship requires keeping both eyes open, or as Chris suggests, wearing blinkers! The choice is yours!
