Hi everyone I have to come here on a throwaway to get a real opinion on this. I think my writing will give away that I'm a real person. Me (25M) and my girlfriend (23F) have been fighting for a couple days about this and while initially I understood why she was upset I now in no way understand her displeasure to the degree that it is. For some context I'm a medical student and have been studying for the past 16 weeks to pass my board exams step 1 and 2 and in celebration planned a trip with my two closest male friends. I gave my girlfriend dibs over my time after my exams ended but she was working and ended up not having any free time before my classes started up so then and ONLY then did I plan it with my male friends. The dates that worked for them given one of them works weekends and weekdays was June 1-9th. My girlfriend's birthday is on the 28th of May which I am promptly ready to celebrate and already have what I want to get her planned and what not. I figured that even tho June 1st was on the weekend that follows her birthday (since her actual birthday is on a Wednesday) that it was okay ONLY because the flight is on the evening of the Sunday. Now here's where I think I messed up, I didn't clear it with her whether it was okay which I felt terrible for. I just automatically thought Friday night we'd have a personal just us thing going on and on Saturday i could get her friends and family to join in and then boom I'm off to Spain on Sunday. However now her anger has evolved from "How come you didn't clear it with me" to "How could you even consider this, it's so ignorant etc etc." It's gotten to the point where we're arguing for multiple hours on end with me apologizing for not clearing it with her to now me being a little upset at why it's this big of a deal. I didn't mean it with malice and I still intended to give it a grand celebration. I have been a little distant the past 16 weeks or so but only because these exams are the hardest exams I've ever done and I need to excel to have a chance into matching into residency as I'm choosing a fairly competitive field. I'd just like some outside input to ground me, am I completely out of line here?
