Do you think he likes me?

I have this really close friend and we've always been close. I've been friends with him since I was a kid. His parents are good friends with mine. Anyway, he started flirting with me and complimenting me which I was rather shocked by. He's called me "beautiful" and once said I looked "hot" and "sexy" at a party. He's even told me how he couldn't stop staring at me once, and how he purposefully sat in front of me just so he could look at me. However, when he first opened up he told me how he checked me out at his brothers wedding. This wedding is nearly about four years ago now. But he told me two years later. He even remembered what I wore. I'm just wondering why he even told me that and why he told me he was checking me out. Do you think he likes me?
