<human>: She is my first gf and I am her first bf too.
Yesterday, my gf was having a hard time because of personal problems and I tried to comfort her the way I could.

Today was our dating anniversary and she sent me a text saying that she was feeling better. We started to make plans but I woke up feeling very blue and irritated. I kind of didnt had the desire to do anything at the time.

She told me "We dont need to go out if you are not feeling like it" and because I was feeling blue and didnt wanted to screw our day I said to her "ok. I think am going to stay home". She replied "it's ok"

Then, hours later, she sent me a message that she was very disappointed at me, that I only cared about her when I felt like it, that I am immature  that she was having a hard time and I didnt went out with her because of laziness.
I told her what I thought and that I had the best intentions but she doesnt seems to understand. 

What can I do to fix this?

Forgive me for my english, its not my first language.

Can you provide a brief overview of the text?
<bot>: My gf doesnt seems to comunicate her needs in a proper way and she blames me when I dont behave like she expects.
