I need some girl advice. How to act post-prom?

Talk to her IN PERSON! gurlz really appreciate that cuz it shows u care more than just the casual text. don't get me wrong tho u should text her too but make an effort to hold a conversation with her. flirt a lot and make it known u like her. if she doesn't like you already then maybe she'll start! you have nothing to lose so go for it:)))
