You married a Thai, and all that family stuff (take care me and Mama etc), Buddhist stuff, good luck crap, making merit baloney, house warming (you are actually supposed to sleep in the new house for a night to give them good luck and blessings), where to place the spirit house for your home and pay the attendant monks for finding the most auspicious place to place it (but if you bribe the monk you can have auspicious placement anywhere you like), and ALL the silly things they believe in or ways to get some free booze and food and a party to break the monotony of the week. And on and on. Want to stop it? Move away from the family, or even the country. Though even then she will likely be prey to family 'obligations' to be sent back home for all the shit they want, guilted, as you have shown you have the money (rich farang) to pay for it all (ALL of it). You need to set limits, learn to say no, tell her what you can/will do and what you will not/can not do. You are now the rich husband, father, uncle, married into their family. And they WILL take advantage of that as much as YOU let them. The wives are under pressure from all sides to provide now she is a rich 'Mia Farang'. Comes with the territory with many families, the poorer usually are the worst (though not always). The larger the family, the more brothers and uncles especially - entitled cunts, and everyone has a hand out for you to solve their issues of money and face (basically begging the wife to intercede on their behalf). All loans will more than likely never be paid back so best to avoid. Learn to shut the hell up and make no promises, cry poor mouth, cite financial problems and limits to your resources. Some of the gals and their families are great (I am lucky, mine are great). Many are not Mr. ATM.
The more lazy c**t menfolk in the family the worse it can be - because they are the privileged swinging dicks and the women are supposed to spoil them and treat them as the masters of the household, even if they provide Jack Shit.
