I realise this might partially fall into /r/relationship territory, but I don't want to deal with this like a bitch, I want to deal with this like a Sedditor.

We've been casually dating 2 months - nothing overly serious. She wanted to come see my hometown desperately, but flaked at 10pm the night before. I was annoyed, but its her loss. Found out she was out with some dude on Friday and had attempted to hide it, but I didn't make a big deal out of the situation. She spent an entire day with another dude yesterday (whom I havent met before). Again I didn't say anything. We're casual afterall.

She has been pretty scant on communication since flaking. I'm starting to bitch out since I've let this girl become part of my life (not oneitis, but Im not afraid to admit I have some emotional attachment).

We have plans tomorrow (lunch date, fun shit)...should I address it or behave no differently? I know she likes to test me and push buttons occasionally to try elicit a reaction but I don't bite - so it could just be this. How would you deal with it?
