<human>: Our mutual friends were meeting at a bar and invited the both of us to come. As we were waiting, she decided to take a nap as I continued working on homework. They ended up calling me about 20 minutes later to tell us they are on their way. I tried waking her up about 5 times to which she vaguely responded "just go". I told her I'm not going to be able to come back if I leave because I will have to go home afterwards. 

Just got a call from her saying she is mad that I went without her and that she thought I was going straight home instead of going to the bar with our friends. I basically said she had no right to be mad at me because I attempted to wake her up and she refused to get. Does she have reason to be mad at me?

Summarize the given text in a few sentences.
<bot>: Girlfriend got mad at me when I went to bar without her because she wouldn't wake up from her nap when I tried to wake her and she told me to "just go".
