I am college and we I see her around campus. She gives me all these iois and recently she gave me an approach invitation by hovering next to me while turning her body and looking at me. I looked at her and turned away I chickened out and in recently she is starting to act cold on me. Although judging by her body language she is still interested but her face is still when she saw me and she seems angry when she saw me. She turned to face me directly again and made brief eye contact before walking away.
I don't want to mess this up with her, she is giving me all the iois there is and I can't do a thing.
I am thinking of asking her for directions and see where it goes maybe throwing a few jokes here and there and walk away. Would that be good place to start?
