Is the Silent Treatment pure manipulation? Does she want me to beg for forgiveness even though I don't know what I did wrong?

I know this girl likes me but she is not talking to me hasn't for a few days. I have no idea what I did wrong. Or maybe she doesn't know how to deal with her emotions? What should I say to her?
