Well if you have already decided to turn her down anyway, and I don't blame you, you could try this approach, after all, you have nothing to lose right?
Email her back and say, "Well to be perfectly honest, that place is a bit more pricey than what I can afford." There is a small chance she may respect you for coming out and telling the truth. Also, doing that you are now putting her on the spot, because if she refuses to go out with you after saying that she is revealing herself to be the snobbish bitch she is.
EXACTLY !!
I really don't see why people are so ashamed to say that some place is too expensive for them.
no bitch deserve that you max out your credit card for her.
hell when I met my girlfriend, for the first few months I was poor as hell and we didn't do any shit that costed money.
sucks but if she stays when you can't offer her a princess life, she deserve to be treated as such later when you have the money to do it IMO
