Tell her that the fiscal crisis has finally hit you (gold diggers are not generally very bright) and that you might loose everything, she reacts like a bitch, she's a gol digger. Go to a bar and say you have no money and ask her to pay if she takes out her wallet stop her because if she likes you for you, she might be turned of that you asked her out when you didn't even have money to pay for the date and feel like your just using her for drinks. If she gets a funny look on her face then you know she's a gold digger :) good luck. Oh and I always find not using any flashy cars and such out that will help you see if she likes you
Well being that I'm a girl who is farrr from a golddigger, I personally feel uncomfortable when a guy wants to buy me things and tell them not to, then again, I'm tha type that wants to do for myself. Sooo I guess if she's asking you to buy or things then id say she's inlove with the money, not you.
