<human>: Give me a shortened version of the text

My girlfriend and I had been together for 16 months when we broke up for about a month. We didn't talk much during that time but were able to fix things (or so I thought) and get back together. 

Today, a few months later, I go onto Facebook and see that she had exchanged some messages between her and her ex boyfriend.

 Curiosity got the better of me and I opened up the messages, and was almost immediately greeted with naked pictures of my girlfriend and her ex, and lots of dirty talk between them. 

I was extremely upset and confronted her immediately about it. She didn't know what I was talking about (or did she?) until I told her I found it on Facebook. 

At that point she fessed up to it and started apologizing, and she also let me know that she was drunk when it happened. I told her basically that I was extremely upset and that I would talk to her later about it. 

That's when she drove over to my house and asked to talk to me about it. (I had cooled down at that point so I was okay with it) She told me that she really wants to fix things with me, that it was a mistake, all of that. 

I don't know what to do from here. Go ahead and AMA if you think it'll help you help me.
<bot>: Girlfriend and I broke up, she sexted another guy during that time, I don't know what to do
