Search Results: making him get excited

So.. Yeahhh.. I like one of my friend a lot, and she found out. My friends told me she sounded very excited, and when she confronted me I just told her "I don't know how I feel about you." So she began ignoring me, always walking by me with a sad face. But we eventually talked it out and I told her I liked her.. But she said we should just be friends and see what happens. But next day, I get ignored. Next day, she talks to everyone but me and when she talks to the other boys she sometimes looks over at me. But sometimes she comes over and just says "Heyyy" and pokes me playfully. So I thought we were on good terms, but next day: ignored. I got fed up with it in class and began ignoring her back. Then today, I continued ignoring her and for some reason she stared at me when I wasn't looking. But I still continued ignoring her and when the bell rang she left so fast that she didn't even say bye to her friends. And I also believe her nose was sniffling, and she looked sad and angry... Would you say it's because of me? And why? When we talked she said we should just be friends and see what happens. I took it as a sign of disinterest as well as the ignoring.
