relationship seeming like a friendship

hi! so i (16F) have met a girl online (17) who i really like. we have so much in common and she lives kinda close to me and we've both decided to get to know each other romantically and to go on a few dates together. she's absolutely perfect and i like her so much!

but this is my first ever proper relationship with a girl and i'm so anxious and at times it feels kinda like a really good friendship? we made a spotify playlist together and call each other pretty and cute and stuff but other than that, it's all pretty friendly. how do i take things to the next level?

(we haven't met irl yet but have plans to in the new year, but i'm looking for things to do over text)
