Major... She sucks you off0
She gives you more attention or asks for your opinion. That's what I would do.
She acts really nervous around you, keeps trying to keep the conversation going even though it's kinda dead, if she knows your goin to be somewhere she will try to be there as well, asks you to hang out alone or even in a group, touches you, laughs at everything you say, doesn't mind being close to you etc.
