We're part of a group of friends who often go to lunch together so that's what I mean when when I say we've 'never' hung out together. We usually sit next to each other in class and walk places together(without the other friends). We both don't live on campus so we don't see each other much at night or during the weekends.
Hanging out all day is what we tend to do, I brought it up when I started to see how it was going and she chatted to me and wanted to 'explain'.geez so you hung out all day, brought up the topic more than once, then went home and chatted on facebook about it???
Bro, you're being way too needy already. Create some distance. Coming off as desperate or obsessed is never good.
