Ms. YF and I have been going back and forth over this one little relationship issue for a little while now.  Two months ago when I sequestered myself away to study for the CFA exam on June 5th, I was holed up in my apartment and reading pretty much nonstop for the week leading up to the exam.  

Unfortunately, that week included Ms. YF's birthday.  But given that she lives about two hours away by mass transit (which is relevant since I don't have a car at my disposal) I had said that I would see her after the exam and do something then.  Perfectly reasonable, right?

However, on Ms. YF's birthday (June 3rd), an ex of mine whom I hadn't see in over ten years happened to be in Times Square on job-related travel.  I was literally about to order pizza for dinner (was even pulling out the Domino's coupons and everything!) when she sent me an IM asking me if I wanted to go get dinner.  My brain fried from studying for the whole day, I said ok.  I even called up Ms. YF to let her know and to make sure it was ok.

Fast forward about two weeks later and Ms. YF is constantly complaining to me about how I ditched her on her birthday (only half-true) for an ex (again, half-true).  I mean, mitigating circumstances, eh?  But the kicker is that this Friday, she's going to go visit an ex and staying at his place for the entire weekend.  

The entire weekend!  

And she's still been complaining to me about missing her birthday.  I'm sorry, I really don't get this.  Did I screw up here?  Is Ms. YF being hypocritical?  Am I really an idiot?  Or am I just an idiot for having told her about meeting up with my ex in the first place?
