There's a girl interested in me that seems like a gold digger.
Why do you think she's a gold digger?
Because she's only interested in me for my money.
It's unfortunate that this woman is only interested in you for your money. It's unethical to use someone for their wealth. Make sure to be direct with her so that she understands that you want a meaningful relationship.
Nah, I need to keep playing this game for some time until I get what I want from her.
So basically you're doing the same what she's doing to you. It's not going to end up well for you both. You better stay away from her find someone else who genuinely likes you.
