I Need Some Advice

So I am an 18 year old college freshman. I just confessed to my best friend that I liked him. I honestly don’t know what to do now. My whole friend group told me that he liked me back etc, but he said no (which is okay). He told

me that he just wanted to stay friends and that he doesn’t date within the friend group. I have already cried but I just don’t know how to feel or what to do, help please!!
