I want to date my boyfriend for his money.
That's bad. Is there anything else about your boyfriend that you like besides his money?
No, only his money and materialistic mindset?
It's generally not a good idea to only date a person because of their money. You should date someone who you enjoy being around and spending time with, not someone who can buy you things.
Shhh, it's all good as long that I get his money and keep my job as his girlfriend long enough to cash in.
It is not all good. He doesn't deserve to be with someone who does not care about him. And you shouldn't have dated somebody that you don't care about except for his money.
