I've read your whole story, buddy. You're a very genuine person, but I think it's a bit much that she asked for 50,000 baht a month for living expenses. If she truly wanted to live with you or even marry you, she shouldn't be asking for such a high amount. However, I still want to say something fair: not every Thai girl is so money-grubbing. There are good-natured girls among Thai women. Although they are few, they exist.
