AITAH for telling a girl ive been flirting with i dont do online relationships?

Hi! About a month ago I (17F) joined a discord server where i obviously got close with some people. Around two weeks ago i started talking with a girl (who lives in a different country than me and we would have no chance of meeting in the near future) from the server and we bonded over a show. Since i wanted to watch it for a long time and she is a big fan we decided to watch it together. We finished watching the show in about a week. After that we started kinda flirting. I didnt see it as a big deal since literally everyone jokingly flirted with everyone on the server. Also i did very obviously state that i do not do online relationships since i know i wouldnt be able to handle the distance (the girl was there when i said it and she saw my message). The flirting started with jokes, then she would start sending me videos like "would u be the x to my y" or the ones with the caption 'us' over a couple. I didnt mind them so i was going along with it. I liked being treated with love. For valentines we traded gifts and the flirting got even stronger. It all happened super fast - in a week or even less. Yesterday tho she sent me a couple of videos about us becoming a couple. My response to them was 'id love to if not for the distance' and i wasnt lying, but im not sure if she took it seriously. I didnt realize how serious things got before it was too late. Later that day i told her that even tho i really like her and im sure that if not for the distance we eventually would get together, the distance still is a big problem and i just dont see it working out. She said she hoped it would work out but she now sees that she was delusional and she understands. She told me she caught feelings for me even tho she tried not to. Im glad i ended it bc the last thing i wanted is to hurt her even more. I still feel like such an asshole for taking this too far without having any real intentions of getting with her. I geniuenly treated it as a lighthearted messing around and it only lasted a week. And as i said i did say that i DO NOT do online dating. AITAH? And do you think its possible for us to go back to being just friends? She said 'yeah' when i asked that but im not sure if it was sincere and i do not want to pressure anything.
