He is not flexible, in my opinion.==>about the wedding he has lived and worked in Thailand and knows some of Thai culture. He will make the downpayment for the house, and you would have to share exactly 50 % of each installation. For me it doesn't make much difference if the house in your name or his, as long as you're both legally married. (of course, there's a small details over advantage/disadvantage)
Well, I have worked with Farangs since grauduation both in Thailand and abroad, mostly executive/ managerial levels. Some acted like your boyfriend. Any way, I understand it pretty well because of cultural difference. But I didn't marry them, and they went for some other women who accepted their terms, which is fair enough ;=)
You just have to let your brain lead your heart. This is the beginning of your marriage/family life. If he never wants to compromise, he will always have his own way--or if you never want to stand up and voice your need, you will never get that right again after marriage.
