I officially hate boys

There was a guy I liked. I told him I liked him and he said he liked me to,with is cool. But the next day at school everyone came up to me and said he don't like you. Of course being stupid me I didn't believe them. I told him about it and he said they lien. He sent me a screenshot of him telling my very close guy friend that he liked me. I asked my guy friend and he said u don't wanna know. He just told me what he said . And I'm confused and upset as way he lied to me over and over. Hopefully I'll make it through this school year😪
