HELP ME!!!!!!

So tell me why I have a huge crush on this boy and I tell one of my friends and the next thing you know he ends up texting my friend saying that he doesn’t like me and I guess someone was behind me when I told my friend that I liked him my heart literally sank when my friend told me that he didn’t like me😞

And then the next day I have school and he won’t even look at me or talk to me.And the worst part is that I sit right next to him in a class and when we have to do group projects he talks to his friends and ignores me😭😭😭. I don’t know what to do please help.
