Is he just messing with me or is he interested?

So this guy that I have a second semester class with is so cute. I thought that about him on the first day but I didn't know his name. Then this guy added me on Facebook and I didn't know who he was but I thought it was a different person. Anyway the guy that added me had liked my picture. So I went to his profile and it turned out to be the cute guy in my class and I started freaking out. And then I like his profile picture because I wanted him to notice me and he did and I posted another picture a day later and he liked it.
Then in class he stared at me and made eye contact with me and when we looked at each other, it felt like there was something there. Anyway he started sitting behind me and asked me for gum once and I gave him some and when I handed it to him, he looked into my eyes and it was magical. And after that he liked my
Changed profile picture. But the thing is he smokes and drinks and hasn't messaged me yet. What's happening??
