Do you think he's overreacting? What's his deal?? Please answer?

There is this guy that I've kinda been infatuated with for the past couple of weeks. On my bus today (I'm a senior), everyone in the back of the bus (all of my friends) was in a bad mood, which got me down. When I'm close to my bus stop I move to the front, which is where he sits, and I sat in front of him today. I was in a bad mood from everyone else being in a bad mood, so I didn't even acknowledge his presence. He just sat there and looked at me. When I got off the bus he sent me a txt that said, "Okay cool ?" The way I see it is, the road works both ways. He could of just as easily said something to me. When I got off the bus I walk with a friend and he made me laugh and smile. I think my guy saw this and it made him mad or something. I told him through txt that I was just in a bad mood and I'm sorry. He never sent anything back so I ended up sending 10 txts in about a day. I know he saw them. I'm pretty sure he's mad at me. Is it really that big of a deal that he can't even talk to me about it? What's going through his mind? Do you think he'll get over it and forgive me?
