Okay, context:

My friends for the past couple weeks have been planning to go to Universal tomorrow on Friday, it’s me and two others. I’ve been super hype to go but today my girlfriend had a horrible day at work and her whole week’s been awful in general. I haven’t been able to see her at all because college, and Friday is the only day both of us would have “free.” 

Im torn because on one hand I made a promise to my buddies to go to Universal and it’d be fun, but on the other I want to go and comfort my girlfriend on the one day she’s off. I care about her and want to make her happy, but I feel awful for potentially throwing away two weeks’ worth of planning. Would I be an asshole if I told my friends I couldn’t make the trip?
