Well I do have to say that she has that attitude only when texting. When we are together, I totally control the frame.
She used to text me a lot before, in fact too much. I got myself a rule: Don't text unless you want to ask her out or she texted you first last time. So I texted her to ask her out, we live close to each other (20 minutes walking), and I told her "Hi im at the park with a friend, come over" and she replies, in less than a minute, "Hi, im at the mall, alone
". She uses for sarcasm. I replied "Come here". She says "No". I asked her why not, she replies "Cause I'm here fucking doing X and you are over there doing fucking nothing that's why". I didn't even bother to reply. I decided to text her later, as if nothing happened. So I texted later (about 4 or 5 hours later), and she still got that bitchy attitude. I told her "I'm going to sleep gotta wake up early, sweet dreams". Her reply "OK 
bye", an image with a 9gag post that says "Arguing with women is like getting arrested cause everything you say can be used against you" and ";) you know".Charblad, she called me on wednesday after the Real Madrid game, just to ask who won (she's RM fan, I'm not). After a while, there was a silence, I had nothing to say, so she said "well I'm gonna hang up", I replied "Ok bye then" and I hung up.
I guess I'm kind of a dick sometimes. I know she didn't want to hang up. Im just GUESSING that's why she's acting like that.
