<human>: Can you provide a brief rundown of the text in within 3 sentences?

I have been dating "Gina" for eight months. She works in a vintage record and book store. I work in accounting. Gina is going to community college to earn an associates degree in business. After that she hopes to transfer to a four year school.

Our relationship has been progressing normally, up until the last month or so. Gina says she wants to move in with me. She lives in a studio apartment. My apartment has three bedrooms, one of which is my home office. The other is my home gym and the last is of course my bedroom.

Gina says that I have plenty of room for her. I told her I do not think it's a good idea. When she asked why, I told her it's because my apartment costs [X amount of dollars] per month, while her apartment costs [X]. She will be completely unable to pay half of what my apartment costs.

Furthermore, I told Gina that while we have been dating for eight months, waiting until we've been together at least a year or more is more appropriate if we're talking about cohabitation.

Gina says that if she lives with me, she can finish school faster. When I asked her why, she said it's because I can afford to have her live with me rent free.

I told her I wasn't comfortable with that idea, and she says I'm being selfish and that I don't take her seriously.

I'm meeting her for dinner tonight (FYI, I always pay) and we're supposed to discuss it more.

Any advice?
<bot>: My girlfriend thinks I am selfish and superficial for not wanting to let her move into my apartment. It is much larger and more comfortable than hers. I think she will be unable to pay for her fair share of the apartment.
