AITA for unfollowing a girl who kind of played with my feelings talking for a month

I (25m) followed this girl (23f) I once had a class with in college and she followed back. Shortly after this, she kept liking my stories on IG. Literally every story I posted, she liked. I started liking hers. Then she slides in my DMs and asked if I wanted to be friends. The conversation took off from there, talking all day everyday about random shit and deep stuff. We eventually met up at a park and talked for hours until it got dark. It all went well. I walked her back to her car she offered to drive me to mine which was like 4 cars away and i couldn’t tell if that was her being nice or trying to get me to make a move. I’m not really a type of guy like that like I actually just liked her and I wasn’t trying to do anything sexual. Anyway I was in her car and it was sort of an awkward goodbye. I didn’t care because I thought it went well over all. I really enjoyed myself and didn’t want it to end but a few days afterwards that all too familiar feeling of slow replies and vague responses came. She eventually told me she doesn’t want a relationship rn. I was upset and couldn’t stop thinking about how much I liked her. I told her I was looking for a relationship and that I couldn’t just be friends. We haven’t talked since then and a month later I decided to unfollow her on IG. I removed her follow from my account as well. Out of no where she texts me all angry that I did that. Saying how I’m weird and need to relax and how she was really hoping we can be friends. She sent a few paragraph texts making me feel really bad about myself.

I didn’t even respond to her because I feel like it’s a waste of time. She makes no sense to me and I don’t even feel like trying to reason with her.

I know from the beginning she said “do you want to be friends?” So you might say I should have expected that But she kept flirting with me and telling me how attractive I was. I really thought it was a no brainer.

But I feel like a dick now because I’m like did I just play with her feelings or is she just being unreasonable. Like if we both have different expectations out of each other then it probably won’t work as a friendship
