My girlfriend is poor?

Every time we go grocery shopping or something she goes “r u paying or am I paying?” Like she doesn’t want to pay for food cause she has bills and stuff. Makes me feel bad for saying no cause she’s helped me so much so ok just go okay I’ll pay. But I’m from a dif country so the currency fucks me up. I spent almost 1100 in less than 8 hours in my country’s currency. I feel like I’m settling and need a richer person. I don’t like grocery shopping cause every time we go I feel like I have to pay. She comes from a broke family and I don't know what to do?
