Should I make the first move?

Now I have a crush on this guy who asked me to prom, and we've bee talking to this guy off and on for about two months (texting and facebook chat with like 2 hour conversations each time that usually he intiated) but for the past week and a half we've only texted once (which I initiated).It is exams and stuff but I figure he would make the time, but whatever. Two of his best friends independently told me he liked me without me asking them,and he acts different around me than any other girl (nervous with me, slick with every other girl). His friends also told me that he he won't make a frist move and that I would have to. This is true cause our friends shoved him into a room and then me with him at a party and he layed down on the bed first and then I did to and we talked for what seemed like hours. I kept waiting for him to kiss me, but then (as we were both drinking at the time) he felt nausious and despite his saying he was okay, I said we should get him to the bathroom so we left. Then at the end of the party he gave me 2 really long hugs. Also we went to prom together and we slow danced and then he hugged me at the end and I felt something, but that could just be my imagination. Then today was the last day of school and he wrote really nice things about me in my yearbook, that he was happy to have had me as a date and closed by saying not to be a stranger so that we could chill during the summer. I looked in my friend's yearbook (who is friends with him as well) and hers said general stuff and see you around during the summer. Should I forget about all of this or should I suck it up and make the first move?
