I think my friend is depressed

So this guy, at my high school has known me for like 2 months. We sit at lunch together cause he doesn't really have any other friends, anyway, he asked me out and I declined because my parents are really strict, and he was really awkward about it. A couple weeks later he asked, hey if your parents weren't so strict would you go out with me? I said no i like you as a friend, he just said ok and walked away. Anyway, so I don't go to that school everyday only 2 days a week and so today I was having lunch, and he seemed more cheerful we don't really have that much in common and im a couple years younger and I like him only as a friend. Anyway, after lunch I said "Hey, I'm free 6th period wanna go hangout in the caf?" He said sure and we went our separate ways. 6th period rolls around and instead of going to the caf he takes me to one of the music practice rooms and im like uh......wtf is he trying to do. He puts on some music and just breaks down crying. I didn't know what was happening but I kept cool and asked what was wrong, he went on this long depressing story and I tried to comfort him as best I could, hugging and leaning on each other but I noticed something, his eyes were red but there weren't any tears falling or watering up. Maybe it's nothing but idk I think he maybe was just trying to get me to hug him or maybe even kiss him? Probably not, he did sound really depressed and he makes some depressing posts on Facebook...I just never know what to do, I want to help so bad but I don't know what to say and I don't know what to do. What do you think? Tell me in the comments.
