At school today, I called out to my gf that I had to go to the school Admin to hand in some paperwork and asked if she wanted to come with, but she didn't respond. So, I called out again, but gave up and walked off. But when I came back, she was walking with one of her friends to the bathrooms. So, I walked off so school parade began after 10mins. I emailed her asking why she did that, but she just said that she wanted to go with her friend so she can go fix up her hair for school photos in FOUR HOURS time and because her friend didn't want to be alone in the female bathrooms (where no one else can get in, mind you) for THREE MINUTES!
Am I in the wrong for getting slightly irritated and ignored, or am I in the right (for once)?
