So... at the end of last school year I told my crush that I like him. He said that he liked me too but we were never officially together.

So, now I am in 8th grade and he still likes me and he thinks that I do too, but I do not. How do I let him down easy? or tell him that I don't like him? Or preferably, how can I act so that he will know I do not like him anymore?

Thanks for your help!
