Boyfriend hasn't talked to me in almost a week... What do I do

I'm 17 and my boyfriend hasn't spoken to me in almost a week. Thursday was the last day I heard from him. We kissed before going to separate classes. I was heading to lunch at 11 and I see teachers and our guidance counselor escorting him to the conference room and he's crying his eyes out and he doesn't do that. He's a very ken don't cry type of guy. They made us all clear out the hallway so I couldn't ask what was wrong. I texted him when I got home but he hasn't been active or at school since Thursday. What do I do?
