Would you be bothered at all/ feel a lil used if you were dating someone and you took them out to eat a lot n they never repayed the favor?

Like I've been seeing this girl for months, and I'll take her out a couple times a week. Sometimes going out to nice places, getting drinks, and usually paying the whole bill which is like 60-100 dollars depending on where we go. Now Sometimes if we go somewhere cheap she'll pay for her half but still she's never offered once to pay mine. I understand that the guy should take care of the bill n all that, but i jus feel like it'd be nice to be taken out n treated like i treat her atleast once. She doesn't work n lives with family while i work full time so i understand that she needs the money that she does get from the government n her family but still i jus feel a lil used
