<human>: I've just left for Uni and me and my girlfriend have decided to try long distance. It's not going well. As the title suggests, she's pissed at me. Whenever we speak, we can't speak about my life at Uni without her going in a mood. Speaking about her life is fine, she's happy and bubbly, but when I start telling her about my day she reverts to one-word 'hmms' and 'okays'. She freely admits this is because she's angry at me for going to Uni. She thinks I've abandoned her.

I go to a very good Uni and it's really, really hard. A lot of work. I'm busy all the time. Of course some of that is social, but I think that's understandable when I've only been here two weeks and I'm trying to make friends. So yeah, I have been giving her less attention than when we were in the same city and I had only free time, but surely this is understandable? The work also leaves me stressed, the calibre of people here makes me feel unworthy, and I can't talk to her about this without her getting in a huff.

I'm being punished and, in my eyes, maybe you'll disagree, I haven't done anything wrong. I know once I go back home she'll be happy again but I don't what I can do whilst I'm here Train tickets are too expensive; we're both quite poor, especially me at the moment. 

I understand she's lonely without me there - I'm lonely too! - and I know she's being like this because she's sad, but I don't feel (like she does) that it's my fault. I'm not going to give up my education, that's ridiculous. I don't think she'd want me to. She's being irrational like that, knowing I can't change the situation and being mad anyway.

We've spoken about the issue a lot and nothing changes. She keeps saying she'll try, but she never does. It's really getting me down. Any advice? Any other students doing long distance?

Can you give me a shortened version of the text?
<bot>: girlfriend feels I've abandoned her by going to Uni, is being very standoffish whenever we talk, don't know if it's worth the stress in the high-stress environment I'm in.
