I don't think that is quite right, and why wouldn't you want to know what you were funding??
My Mahal may be going back to Phils if she does not get a continuation visa in Singapore, she is worried about that, so I said that I can help support her. So the very first thing you need t oknow is 'exactly' what the monthly expenditure is. Water, electric, gas, internet, food etc etc. Make a list, make sure you are happy to help cover the simple living costs. Of course you want to treat your lady as a princess, treat her to the nicer things in life, and if you can afford it, do it. But what I mean to say is that you have to budget, and not be an open wallet. I suppose it is a case of mutual respect.
