My girlfriend and I split it according to what we order really, I tried to pay for her at first but she very quickly said she would pay for her own food 
Something for which I am very grateful, because food is expensive, and we wouldn't go out any-more if I had to pay XP
The same goes for anything really, I haven't the money to pay for her and she hasn't the money to pay for me. And damnit do I get annoyed when other people say that I should pay for her or we should pay for each-other's stuff, particularly when said people telling me this are in rich families -.-
