Plenty of Filipinas have determination. My wife does and I respect that and encourage it too.
I don't personally know any that are money-oriented in the way you describe.
If my wife want to do something and we can't give a priority to that spend or if we have no budget for that then it doesn't get spent.
It's a two way communication but I can't think of a time it caused a major argument or nastiness.
It's always difficult to give any advice when each persons perception is not known.
But if you truly aren't able to do something then you must tell her that and tell her why.
