What are we?

Okay, so I have a new found best friend and it's a guy. At first I thought I could like him but then he majorly friend zoned me, and I was okay with it. At school we are the center of jokes and everyone thinks we should be together. He's with me basically 24/7 whether it's at school or he comes over to my house just to watch friends and cuddle on my couch. The subject of us being more than friends has come up in conversation with us many times, and it's always the same thing "you're just my best friend" "I don't think we would be right for eachother" etc.. but sometimes it feels like he's trying to convince himself. He's also told me that he's contemplated kissing me a few times, and that subject also keeps coming up especially because he's taking me to prom with him (I'm a sophomore, he's a senior) and he thinks he might kiss me at the dance. I think I still have lingering feelings for him from wondering what could've been before he friend zoned me, but is it because everyone tells me we should be together or is it because I actually want to be with him? Also, does it seem like he could possibly have feelings for me?
