Should my girlfriend pay for my food?

I’ve got my own house, I’ve got bills to pay for. I’ve not long spent 8 k on a holiday for myself and my two kids and when my girlfriend comes over, she only pays for her food. But she only stays over at weekends. Doesn’t give me any money for the bills. I earning more money than her. We do live 30 miles from each other and she is the one doing all the driving. when it comes to food we keep it 50/50 is this fair enough?

should she pay me
