Thank you all for your contributions. This was a very useful and interesting exercise. Many different experiences, many different opinions so it definitely worked.
For those of you who were interested... at some stage of a relationship is was my idea for her to quit her not very well paid, not entertaining and without any career prospects job. It allowed us to spend more time together, travel to South America together last year and have a home being taken care of by her this year. I'm more comfortable with this than sending her to a similar job she had with similar conditions and salary. Better ones are probably out of the question. More education/experience in the fields she started to pursue would not probably change much and even if... I mentioned before I'm happy with a natural, historical division of duties between sexes.
She mentions every now and then she'd like to run her own business, a restaurant maybe. I am open to the idea. It could be a hobby, her own money stream if she makes it profitable... but she always wants to travel, have a dog, and have babies in a not so distant future so I am threading lightly on any potential investment ideas. Women don't know what they want or they want everything even if what they want is contradicting (running a restaurant and travel?). Young women even more so, but let's leave it as it is. We will see how all of this develops.
Yesterday more drama unfolded. Basically she sent 15,000 as a standard to the family in the beginning of the month plus 2,000 for Chinese New Year. Two days ago they asked for another 2,000 to open a new bank account because the old one is no good (WHAAAAT?). When I questioned the narrative, it turned out that it's 1,500 for this mysterious insurance and 500 to open a bank account. I couldn't be bothered really as it's still within her 20,000 allowance. I advised not to send this 2,000, but she did anyway. So they came back yesterday. Now the door is broken and it will cost 10,000 to fix it. In other words buffalo is sick and it looks like a door.
I told her to say "no". She is considering spending the rest of her little savings from last year to have it done. Again, I advised "no" but I also told her that it's up to her if she always wants to be broke and send every baht to them no matter what. This way or another, I am not giving more. Not now, not ever unless like some. of you said - there is a major emergency and I'll have a proof of that.
The situation is a bit tricky because in the end it's not even about the amount. I could give her more so she could send more. But what would be the point? Where would be the limit? I am trying to make her aware that greed of Thai villagers have no limits. Send 20,000, they will want 25,000. Send 25,000 and they will want 30,000. And the limit will never be there in my opinion. The tricky part is that we have a great lifestyle and they can probably see/sense that. In my view, however, the fact that we can have it does not automatically entitle her parents to have it too. I don't want them to be poor or suffer, but I am also not going to buy them a villa with a swimming pool if you know what I mean. And they probably will never be ok with that especially if one day we buy one for ourselves.
Last, but not least... her father was of course already thinking about coming back to work but on his own terms. If only he had a van or a car for a taxi... well, yeah, to hell with that. I am not buying let's say a 1m baht car just to pay for its insurance, gas and service later on top of my gf's allowance just because he can't find enough clients to make his new business sustainable.
The conclusion for me is that I'll keep giving her what I committed last July as long as the relationship works. What she does with it is her choice. I won't give more and if that's not good enough - here is the door. If there is any funny business (like a second "boyfriend) on the side to get more money - here is the door. Love is great and all but my life would be equally good without her. Just different.
Thank you again for all your contributions. I am checking out for now.
