<human>: So a little background.  With a girl who I was with for 3+ years but we are currently "working on things".  We still go out and she spends the night sometimes.  But graduation is approaching for me in a month and I have a class which I'm barely getting by in (68%).  I have my last exam before the final on Monday and have spent a little bit of time during the week studying and planned on not doing anything on Saturday & Sunday just so I can grind some study sessions.  She wanted to go out or hangout tonight but I told her I didn't want to do anything or have her over because I know I won't get any studying done. The problem is my S/O is telling me I am selfish and that I am "caring about myself like no one else matter in my life".  Am I selfish for  not wanting to do anything?  After all I'm doing this so I don't have to stress (as much) for my final and ultimately so I can graduate in a month.  Am I in the wrong?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My S/O says I am selfish for not wanting to do anything tonight and tomorrow because I want to study and get a good grade.  Am I?
