Is this the end?

I started talking to a guy (literally a week ago) and I really like him. But yesterday, I made kind of a mistake. He said something (by text messages) and I took it the wrong way. So, I went a little angry and now I feel like he doesn't like me anymore. Cause when we started talking, we had really good conversations and I think he is/was into me. 
Today, I stayed at school for a longer time('cause I'm 13 years old) and he was there. I was seating on a sofa (we have 2 sofas in our school😃)with my friends and he was seating on the other sofa. The sofas are really close to each other. I looked at him and he was all red(like he was shy because I was close to him.
I'm just really mixed up right now. Does he still like me ? Or he hates me ?
