<human>: Can you give me the gist of the text in a nutshell?

Hi,
Im having relationship trouble with my girlfriend. She started working about 5 months ago after graduating. When she gets home she is angry, tired and irritated, If I do something wrong she glares at me or yells at me.
I try to make everything easy for her (I know she is stressed from work and getting up early) by basically performing all duties at home (this while working on my thesis and studying full time, I also work on the weekends).

If I ever bring up that she is hurting my feelings or get mad at her in turn she explodes and screams at me that she isn't allowed to ever be tired, she screams and screams until I basically wuss out and apologize for ever saying anything just to get it to stop... This has gotten to the point that when she starts screaming I know we can't have a discussion anymore and I try to say the right things not to get her mad.

I don't know what to do... We have talked about this and she told me she would try to act better and insist she loves me but every time she starts screaming at me it hurts so much... I really love her.
I also get hurt that she makes an effort to behave with her friends and family but never on my part. At first a thought it was a transitional period starting a new job but now, 5 months later, I fear this will never let up. We never had this problem when she was studying. :(
<bot>: Since starting a new job girlfriend gets angry at me all the time and I cant seem to do anything to make her happy.
