Most Helpful Girl
I'm pretty sure he was enjoying the time he had with you in the car! Lots of eye contact, smiling and conversation are all good signs. I'm pretty sure he wanted to kiss you, i mean what guy would just sit in a car with a girl (unless you're platonic friends) and just stare and smile at her? Next time if the moment is like that i'd just be like "ahaha you're making me nervous or why are you staring at me?" and smile back and see how it goes.
