I think this is a wind up post cos most wouldn't post this question in the 1st place but ok let's play. First, you will never be accepted into the Thai family, Second she will be seeing the thai b/f in the Village who has sat back taking most of the 20k you are giving her, Most village people in Issan scrape to survive they certainly cannot afford to gamble frequently, as posted we in the west understand when we are being lied to and respond Thais do not, they believe lying is normal and is acceptable. No point confronting her or sneaking around her village as soon as they get a sniff your checking up they will stick together and lie and you will get " Darling I love you I would never lie do you not love me " and as with most who are ruled by there heart not their head that they cave in. Man up ditch her and move on before your left potless.
