Thank you for your response, Mr. Romantic. You've been extremely helpful to me thus far and I'm very appreciative. In this time of emotional loss and confusion, forum members like you are to be treasured.
To be honest the PI idea popped into my head before but since I reckon it will cost a bomb (and I personally don't find it very respectful - I'd be mad if she did it to me) I think I'll have to look past this. I can handle the truth but I don't think I want to spend so much to uncover it. Just a practical man speaking.
G-Club girls, even if they end up sleeping with their customers, don't get paid for it - this I'm pretty sure. They're not pros and whatever they choose to do outside their own work hours (like sleep around freely with handsome strangers) is entirely up to them. I think your analogy of G-Club girls like RCA girls are spot on - after all they're young, attractive and have absolute liberty to sleep around a little bit with whom they desire. I don't think any of us are in a position to control or deny the existence of this facet of Thai life.
I can say for sure that her priority is with her family and earning enough money - for now. I'm ok with that. I guess I just want to be sure at this stage that she's not bringing me on a futile emotional ride.
