Girls, you know better, what should I do?

well it sounds to me this girl either was texting someone or she was just doing the 'fake texting'. many girls do this in awkward situations so there isnt any awkward silence. The fact that she was on it all night might be a sign of not interested or a sign that she was just nervous. since you guys exchanged numbers i think, since your the guy, should send her a text saying 'hey' or 'whats up' if shes not interested she probably wont reply. but you will never know unless you try right? fav quote, 'dont regret what you did, regret what you DIDNT do' think about it. good luck!
