It sounds like she's not interested in you as anything more than a friend and the idea that you might want more is putting her off. The fact she told someone that she suspected you liked her and THEN starts avoiding you seems to fit that scenario. I've gone the "come clean" route and it doesn't work unless she's into you, which she'd be letting you know by her body language and making herself available. The fact she's not talking and evading you is pretty much the opposite of that.
No offense intended, but you sound like one of those insecure guys that girls have around to use when its convenient for them but don't want anything romantic with. The best thing you can do for yourself is to not focus your energy on her. Get involved in other things and meet other people. Girls like guys who have something going for them, not guys who are needy and clingy. I was like you in college. I had a lot of girls who I was friends with but they would end up dating my guy friends and coming to me for emotional support. When things were back on track for them, I got kicked to the curb. The thing to keep foremost in your mind is that you are always "cool" with the way things are. Whether you out your feelings or move on, always be nice and say "hi" when you see her. Don't expect much if anything back. If she wants to talk to you she will and unless its anything but chat, you need to let her know you have to go b/c you've got a thing somewhere. You don't want to slip back into mister "nothing going on".
I'm not saying be a "player", I'm just saying be yourself and everything will fall into place. The more time and energy you spend trying to fix this situation, the further from having what you want you will be. Trust me, I've been there and it always ends the same way.
Once I was into doing my own thing, the girls I met wanted to be with me, not my friends. I joined clubs, volunteered for vaious groups etc and joined a Frat. It paid off. I was too busy to focus on one girl or another and then you are more desireable and have more options. Years later, I even had some of my old girl "friends" come around wanting more. That didn't happen until we'd had some time apart though so they could forget about me as a "friend" and see that I might be someone they wanted as more.
