She ignored me in public, but now is mad at me for ignoring her

I finally got frustrated with a girl who basically doesn't want to date me, though we tried a few years ago. She's really shy and she had this thing where when there was a bunch of people around she'd ignore me. Pretend I wasn't there. Wouldn't even talk to me or say hey.

And yet I still came up to her and initiated things.

I finally realized I deserved better than that and started to do the same to her as she did to me. It got to the point where I even stopped initiating with her when we were one-on-one and only acknowledged her if she said "hey" to me first.

Well, it looks like I pushed her buttons too much because now she's blatantly ignoring me. Last time, all she did when she walked past me was look at me with a neutral expression and kept walking.

I don't feel all that bad. She's a hot girl, she gets a lot of attention. I'm slightly below average-looking and have to work for attention. Should I feel bad that she's mad at me? I was just doing to her what she did to me.
