I told him I like him and he hasn't talked to me?

So, I told a guy I've had feelings for that I liked him. I literally went up to him and told him that I have feelings for him...I kind of blurted out that we can't be friends because of that. I hate being vulnerable, so I was on the defense from moment one. And...I didn't really let him get a word in on purpose (In cause he didn't feel the same way). I think he was kind of, err, shocked...Either because I like him, or either because I bluntly stated it. Uhmm. I told him because we're going our separate ways after this year, and I didn't want to have any regrets. And in a way, I wanted to prove to myself that I'm capable of putting myself out there once again. I knew that I was taking a risk by telling him, but that's what I wanted - To take a risk. I knew that it may make this awkward, or even ruin our friendship, but I thought being brave and honest is the best option, instead of having it weight on my conscience. However, he hasn't talked to me since then. I'm not hurt at all, but I'm angry - If he doesn't feel the same way he should have the same guts that I had when I came up to him and tell me. I don't think he's ever been in a relationship before, so I think it was shocking for him. He's not a "ladies man" at all. I haven't spoken to him either, and have pretty much pretended he doesn't exist. I feel as though it is HIS job to come and talk to me first since I went up to HIM. Please don't tell me to go ask him, because I will not come off as desperate or needy. So, is him ignoring me, his way of rejecting me? (Its been a week).
