Dude, I'm gonna have to agree with HB 9.5 on the whole "idiot" thing...if the shoe fits wear it. Anyway you screwed up, but it's salvageable if you want to, it might be better just nexting her, as one of the other posters said you guys have a communication issue. This chick is lost and you refuse to get her directions and ignore her? The hell is wrong with you boy? Listen, I'm all about trying to maintain control and playfully tease girls that one talks to, but you gotta learn there's a time and place for that sort of thing. I mean you know this chick is sensitive right? Keep that in the back of you're head when you're texting her, once you know her better and she gets more comfortable then she will pick up on you're humor and or teasing. The second thing you did wrong was take her texts back as being serious, it sounded like she was just teasing you back with the smiley face at the end. Sounds like you got a little bit of "you can dish it out, but you can't take it" sort of thing goin on there. I'm not saying to bow down to the girl, but learn when to stand your ground and when to give in. This situation was not one of the those times. Tough call on the NC thing, if you guys haven't talked yet, I'd hit her up with with something along the lines of what DonJuanabe said, but keep it playful.
