if u cannot afford to help her tell her straight...she would understand it for sure. Secondly 7000 pesos a month is too low for a months salary i remember that was salary my in phils 15 years ago and still struggling lol. So its probably more or less break-even or not enough to pay her daily expenses. And third dont worry too much that she's taking advantage of you just b'coz you're a westener. Even filipino boys do give money to their gf so its no difference at all. Most of my cousin are all males and i tell you their gf knows their finances rather than their mom.
