My date keeps paying for our dates

I met this girl on tinder and we matched and talked we had a connection sort and i asked her out , she shows up 2 hours late for the date and we still had a cute date and we went a small bakery/ cafe and had milkshakes for which I paid. Now we have been going on for 5 dates and I loved all of them but she has been paying for most of them even after fighting at the counter for paying the bill. Now i don’t want her to keep paying for it and she has been telling me this is how she expresses her liking for me should i be doing something ?
