<human>: Give me the gist of the text in a nutshell

We're both 19. I'm 3hrs away at college, and my girlfriend won't be here until next year. She tends to ball up when she's upset, and this is no exception. We've been together three years.

I can't help that my prof gave me an assignment over the weekend. I had even told her earlier this week that I probably wouldn't be home this weekend, before I even knew about the assignment. But she's still upset. This is the first weekend of the semester. I've tried talking to her since, but she says "I'm not upset, you need to work. Good luck." I'm sick of being made the bad guy for having homework.

We don't live together, btw. Just in the same town.
<bot>: GF and I are in college, same hometown. She's at home this semester. I can't come home this weekend, she's balling up because of it. What can I do?
