My friend is having a big birthday party at the end of the month. We go to the same university, but she's an undergrad, and I'm a law student. Because of that difference, my finals start a week before hers do. Her party is before her finals, but during mine.

She changed the date of the party at one point, and it was initially going to be a week earlier, so before my finals would start. I told her I could go to her party then. After the change, which she reminded us about in a group chat, I texted her outside the chat to tell her that I wasn't sure if I could make it with the change in date. I didn't outright cancel, but said that I needed to focus more on my studying, so I'd try to stop by her house when everyone is there, but I can't go to the other end of the city for the second part of her party.

She tried to use the fact that I went out with some friends from class after our first final, but that was because that was the hardest (and first ever in law school) final of the semester, and we had almost a full week until our next exam (they pity the 1Ls at my school). I only stayed out for maybe half an hour (didn't even drink) before I went home to study more. 

She's also mad because I'm going to another mutual friend's birthday party tonight. I have homework, but I've already told my friend I was leaving super early (after arriving late) to do it. Basically a "hi, happy birthday, here's your present, bye" situation.

She told me other people my age (she's a few years older than me) didn't have the same problem, and got mad when I pointed out that the other people my age either graduated and weren't in grad school (therefore no finals) or were undergrads (therefore a later start to their finals). She hasn't talked to me since that conversation.

I can understand where she's coming from and to an extent why she's upset, but I really think studying for finals is way more important than a birthday party. WIBTA for skipping?
