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

Being that it's a really long complicate situation, I'll talk about only the important points.

We were talking all during summer and had casual sex everyday. Now  that school has started we don't spend time together, therefore, she decided that it'd be best for to just stay friend--most likely so that she can hook up with her ex of 3 years whom she had been "friends" with the entire we were talking. They would hang out over the summer while she was talking to me. But now that that is over, it is only logical to presume she had sex considering she lives closed to him and that she said to me that she needs sex so if we're not having it she'll end it and find it somewhere.

Fast-foward now, I was just recovering from her ending this then yesterday happened. We went to eat, we're talking about stuff then she said she hasn't gotten over me and still had feelings for me. I told her the same, I'm not over her, etc. But she noticed by medium of Snapchat that I've been snpactting someone very often, she's the first then the person is second. She asked about, now that we're just friends I thought it'd okay to tell her that, I met up with a crush and been hanging out with her.

She emotionally flipped out. She started tearing up, she wanted to get up and leave the restaurant. I convinced her to stay because it made no sense as why she was acting like this. I asked her what's wrong, she said she doesn't want to talk about it with the person who caused. That hurt me a lot because I don't understand how I caused pain on someone who ended things with me. Even if she still had feelings and she was hurt by all of this and maybe feels jealous and alone, but that's exactly how I felt when she ended things with me first. So I am at a lost as to how she thinks I'm the bad guy here...

If you want clarification because I understand there's a lot of information that might missing, just ask.
<bot>: Girl I have been talking to for 5 months ended things and we stayed friends, I told her that I was hanging out with a crush and she emotionally flipped on me.
