How does a girl act when she is hurt?

As in hurt emotionally? I was a jerk to this girl, she says she is fine but her behavior has changed. Can you give me some of the signs?

She says she is fine. But I can tell just by the way she talks to me (and even other people, lets just say she isn't as chipper and it all started the day we argued) and by the lack of eye contact or even a hi that she isn't fine.

Well, she told me she didn't care if I talked to her or not ( of course, her actions say otherwise because we are always talking) and I told her I'd be very happy if I never saw her again. She can say whatevet she wants, maybe she meant it or not. I said mine out of anger just to upset her, of course I want to see her again. We haven't talked since, we just ignore each other. I can feel this weird feeling (maybe its me) that we want to talk, but are holding back
