Was she disappointed? 😥 would you be disappointed if you were in her place?

So.. I have a little crush on this one girl in my class and both of us are good friends and book lovers..so a few days ago she has suggested me a book and I had bought it. Today she asked me how's the book did you enjoy it and stuff.. well I didn't want to lie.. so I told her the truth that I didn't read it. Then she said ohh ok or something and went to talk to her friends.. 🙄.. was she disappointed by my answer?.. would you be disappointed if you were in her place?
