How can I get him to stop hating me?!?

OK, So the guy I like is a little silly and he farts a lot in cl. I know it sounds gross but hes TOTALLY cute and a couple of days ago I wrote in his year book that he is weird and his farts smell awful (i know it was mean but i wasn't done) . Before I could say something else he took the yearbook away and ripped out the page I wrote in. Now his friends are all calling me mean and I tried to tell him sorry but he didn't forgive me. How can I get him to stop being mad at me?
