<human>: Can you give me a shortened version of the text?

To give background: my girlfriend has anxiety and is quite depressed. Sometimes she gets in moods where she doesn't talk to me, and it's hard for me to determine whether she's ignoring me (she does it when she's mad) or just in a "mood". 

Today, she got in one of those moods, and I tried to talk to her to see what was wrong. She completely ignored me and didn't even bat an eye. I needed to do something important, so I went to do that because I didn't have 30 minutes to spend trying to talk to her. I even got a bit upset with her and didn't talk to her for awhile.

I had headphones in and I could see she tried to talk to me, but I was upset that I always try talking to her with no attention, so I ignored her. Eventually, I took the headphones out and we talked.

Tonight she was telling me how upset she was that I ignored her after "what she said". She tells me that she told me it's over, and never to talk to her again (after me ignoring her for awhile). 

I understand she may have just tried to her a reaction out of me, but I'm hurt by that and take it really seriously. I don't know if ignoring her for a few days would be terrible or overreacting, but I feel too offended and shocked to respond.

What should I do?
<bot>: Girlfriend ignores me. I ignore her for once and- while I can't hear- tells me it's over.
