My friend thinks I like him how do I tell him I don't?

I said I liked his haircut and that it looked cute. he said "aww do you have a little crush on me"... then I said sarcastically "no I have a huge crush on you"... then he had a smile on his face and told me he thinks I'm really beautiful. He bought me stuff that I wanted (even though I said , it's okay he doesn't have to.) and kept hoovering over me. He's acting like a boyfriend. How do I tell him I didn't mean it that way? 😔
