AIO for getting upset at my friend for buying me something and expecting me to pay them back

So me and this friend usually go to this yearly event together but this time, I was a bit hesitant to buy the tickets this year because I’m moving out to an apartment for school and I need to save as much money as possible for such. I told them I would love to go with them this year but we’ll have to see if i could go since it’s gotten pretty expensive to attend the event. A couple days pass and I didn’t realize they texted me about the tickets going on sale since I was busy getting ready for work. When I was able to check my phone they texted me that they bought an extra ticket for me and want me to pay them back. I’ve been pretty upset about this situation since I’ve never fully solidified that I would be going and they know that I’m moving out soon.
