This is how most guys think it's done. It certainly helps but just trying to impress her with the amount of money you can spend doesn't work. It might be an initial interest in the beginning but she'll soon see through the phoniness and that you're trying too hard. Guys forget the personality aspect and it's really how you two connect on an emotional level. If you're not a nice person it doesn't matter how much money you have, she still won't like you!
