i had been living in Thailand for quite a while and still live here. And this are based on my limited experience

When u marry a Thai lady, you are getting married with the whole family. But that also depends on her family upbringing, if she is from Issan ( Nakhon anything, Sisaket, Surin, Buriram, Khon Kaen etc google Issan you will get the idea ), they have far more stronger family values. You may or may not need to splurge $$ on their family. People from this region is poor and generally this women can be found in the night life service industry for tourist. Thai men usually avoid Issan women unless their family background is ok.

If her ancestry comes from China, this is the type that dont expect you as a husband to spend all kind of $$ on their family. They are mostly can be found around Bangkok ( some Thai say/claim 60% of Bangkok native have chinese blood in them ) and not necessary only fair skin type, but nearly all comes from middle class and above, and may have family business, and have better education. But it is not hard to spot, they will have chinese facial feature unless they married out to someone who is not thai chinese.

I have not much experience with women from the North of Thailand, but they are also soft spoken like chinese thai. Thai men are crazy about them, they are more lady-like, have white fair skin and have the largest mammary glands in all of Thailand. Some of them can be found in night life industry that strictly cater to Thai only.

Thai family have very strong family values, it is always family first even she lives in a foreign country.  Some will want you to keep buying the in-laws stuff, want a very big sin sot (dowry) for face purposes. Some dont demand, just a simple gift does it.

15 years ago, you can get any Thai girl if you want if you are from the West. These days, it is more about Chinese.

Those that have live in Bangkok and tasted city life, practically they have no difference to Malaysian Chinese, no difference then any other women who has tasted the benefit of living in a large city. It is the individual character deep down inside that make every person different.

By the way, learn and write the language if you are damn serious. This will open u up to a whole new level.

No i did not wed a women from Thailand, so my experience is low i can only observe from Malaysian friend who married Thai girls and sembang kuat with Thai kolik. And only applies to middle class Thai women.

Thai society has a very strong social class system, if she is poor and have low level education she will have problem like self esteem issue if you take them to a hotel function setting. The middle class/upper class will distance them self from her and hence you.

And no, most Thai girl does not want to leave Thailand. Unless you are very rich in you country of origin or your country of origin have a far more better prospect then Thailand.

This is a VERY GENERAL take of Thai women and does not reflect each and every single one person, so use your brain.
