Not very easy there is many culture and backrounds. If she is Isaan you have one culture if she a bangkok girl there is another. I been married for 4 years and its not easy I think "normal" thai girls act 100 % like bar girls but with some more smart thinking in it. Loads of mind games, testing stuff. Motorbike Taxi spying on you and all that bullshit. If I could reverse mylife I would not have gotten married
Dated and married hi-so girl and believe me they are even more treacherous and cruel than any other Thai woman can be. Always go with a kind heart no matter what level of society they are from. I am single now, still living in Thailand, and know that a kind heart no matter what society is irreplaceable. Cheers!
