Why is he being like this?

This guy I’m into, but I never told him that I like him.. is really confusing me. The other day he straight up told me that he’s not trying to be friends. & that Really hurt my feelings. So I deleted him off fb & told him that & now if I call him he hangs up on me, yesterday I seen him & I was asking if he was mad at me. He just walked away from me. Like why is he being this way towards me?
