IMHO, the whole beauty of Asian culture is that it did not loose (still) the sexuality in man/woman relationship. There is nothing wrong in man pampering his woman and there is nothing wrong in woman taking good care of him. This does not affect the whole notion of independence and roles in the family - girl can be independent all right, pampering her man does not make her any more dependent on him. Likewise, man pleasing his woman does not mean he does not want to be pampered or loved. I for one am tired of corrupted, twisted and untrustworthy relationships that rule western world today.
Of course, many bar girls would not give you the spiritual and bonding relationship that is common for Asian culture, but then one needs to understand that the whole nature of their work assumes they dont get attached to men on the emotional level. This is a barrier built to protect themselves, otherwise it is too easy to meet 20 good men in a single year, fall in love and live through 20 heartbreaking separations - this is far too high price to pay to keep this kind of attachments happening all the time.
Consequently, it is only natural that once one meets a girl he likes and tries to form the emotional bond (or in other words make her fall in love with him) one has a Herculean job to do to overcome all defensive (and often negative) thinking that has developed over years being in business.

Apology for the long post, my point is rather simple - treat BG with respect and tenderness they deserve, give and receive fun, be generous yet not foolish. If you get same back then keep her, if not - dump her. It is all about mutual respect, self esteem and getting most from your life. If you come across someone you think you wanna marry then think many times - are you gonna spend all your life with her or not? If even once you think you would not then keep her as a girlfriend rather than marry her. Asia has a lot to offer to us, farangs...
