<human>: Girlfriend is 21F. I am 22M. We've been dating for six months.

I come home to her last night and she says she's upset because I do not buy her things. She says that I should buy her things on occasion to show that I can be a provider/caretaker/be there for her. I told her that I can show her care and be there for her in ways that don't use money explicitly. (Sometimes when I'm away I drive hours to visit her just for a day, I spend gas to drive us everywhere, I listen to her and give her advice and love...) I don't see why money needs to be a factor, but she says she is "old-fashioned" and "that's just the way it is." She even cried at one point because she was so upset about it.

While I've never bought anything for her explicitly like dinner, I've always not done so because I've always felt that two people in a relationship should treat each others as equal. I do not want someone relying on me financially. Other girls I've dated felt similarly and did not want me to pay for their things.

We've been together for a wonderful six months, and this just sort of comes out of nowhere. How should I react to this?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Girlfriend of six months wants me to buy her stuff to prove I care about her. I do not like this idea. How do I handle it?
