What does it mean when your shy crush becomes more talkative toward you and makes comments to her parents about how cute some guys on TV are when you are around?

Well maybe she wants you to get jealous about what she thinks of other guys, cuz she knows that you know she likes you. That's all I can really think of. And if she's been waiting a while to let you know she likes you, or if she wants to be with you she might be getting tired of waiting and start talking to you more.
