Bar girls in Thailand come in all shapes, sizes and characters. Some are doing the job because they like it, others because they can't find any other way to make money. Some are honest, some not. I have two friends from the UK who married Thai girls from pretty low dives but both have remained happily together for over 30 years. Another, though, was cheated rotten by a girl from a similar background. Main message- take your time, watch your money, and don't commit to anything until you have fully tested the integrity of a potential partner or long term girlfriend.
