I don't see what the problem is here. Everyone earns a different amount so you send what you can afford to send. As has been said previously our g/f / wife managed before we came into their lives. Its only natural as time goes on in a relationship, things become more serious and so will probably warrent more money. After all she is your loved one and so in theory you'd want to be able to provide more and look after her, its human nature. You'd certainly give more money to you wife, fiancee than to a girl you've just got together with, wouldn't you?
THere is a lack of saving culture in the phils because lets face it life is nearly always lived day to day there with little concern about the future because very few can afford to think of the future. I know my wifes family are basically on the bread line so its hand to mouth living day to day. So if money is sent for them its (hopefully) for a specific thing, not just to wazz up the wall. When sending money to the g/f, wife or whatever it'd be for specifics obviously, rent, food etc but if possible there'd be some there for other stuff. New clothes, go to the parlour etc.
At the end of day the day you send what you can to help suplement what she may earn out there. I know that month to month the amount I sent varied but LIza was ok with that. And that is also the other important thing. As long as your other half realises that there are bills to pay, food to buy in the uk I'm sure everything works out.
Trust is another element here, It'd fairly obvious if shes been out partying etc and not paying the rent , bills etc wouldn't it. Next time you visit and its a different smaller apartment or theres no elec, alarm bells would be ringing.
