Do black women only want to use white men for their money?

I have been dating my girlfriend for only a week now. She is african american 5-4, 140 lbs, cute, brown skin, small waist, nice big round curvy azz, and average size chest 36 c. I think I love her and she is my heart the perfect woman. But since we have been dating she has been draining my pockets. I have spent 2,500 on her this past week. I make roughly 250 - 300k a year and I'm only 21.BY the time I'm 30 I will be rich. Everytime we go shopping she picks the most expensive things like designer cloths, designer sungles, shoes, and 14k gold rings. Maybe it's my fault for spoiling her but if I tell her I do not want to buy her something she gets mad. Sometimes she seduces me into buying her what she wants. She puts on something cute and y and I cant resist. I know she does love me because she seems genuwine. We live in a three bedroom apartment in manhattan. She cooks and cleans :-). My parents do not like her and no it's not because she is black. They feel like I am spoiling her and they dont like it. My mom told me she should like me for me and not my money. I love her but I'm confused. What should I do?? Please help
