Just left a girl on read and now everyone in my school is telling me that im an asshole?

So I've been talking to this girl daily for over a year now, and just recently I've stopped because I feel like she doesn't want to talk to me anymore. Signs such as cold ass messages, late replies, not even responding to my goodnights, n'allat shenanigans. So obviously, I thought she just doesn't want to talk to me anymore or more-so her losing interest towards me. What did I feel for that? It sucked, dragging my weeks of her just not even putting an effort on holding a conversation with me.
From talking to her until 3am; to spending 3 hours conversing; to barely even holding 3 minutes of messages; to now just not interacting for 3 days...
And now people in my school thinks I'm an asshole??!?!?
I might just be exaggerating though but man does it suck
