On a serious note, the question I have is, how does the fact that she comes from money help your life?
She can be a rich girl, but if she isn't using her money to help you in any way, then it doesn't matter how rich she is.
Personally, I'd be on the come up, other pussy isn't going anywhere, get the most you can out of the situation, you can always get out later if you feel the need to.
Look up guys like Chris Judd and Casper Smart, they played the game perfectly.
