Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Input: Please read before judging. My girlfriend (18) and I (17) dated for a year and a half, before I broke up with her a little over a week ago. Now, I realize I am the asshole for how things ended. I broke up with her over text, as we were in the middle of a bad fight and I realized I couldn’t do it anymore. I just didn’t want to arrange a date just to break up, and I realize that was terrible. 
So today, I took her to get dinner so that we could talk, and when I asked her what she had been up to she said “partying, hoeing, working, school, hoeing, partying.” And I said I was surprised that she had been physical with other guys so quickly. She said “I don’t know why that surprises you, but we don’t have to talk about it.”, then proceeded to mention him several times (“he drives a $50,000 truck, he’s LOADED” etc.), which I tried to ignore, until she said “I need to look for a prom date now, maybe I’ll see if daddy wants to go with me, except were not really a public type, if you know what I mean.” I immediately became distant, and went to the restroom, when I walked out, she was walking towards the door and said “oh we don’t have to leave”, to which I responded “you were the one walking out the door”. 
On the way back to her house, she became very angry at me, telling me I had no right to be upset, etc. I explained that I was not upset about her being with other guys, but I would like her to keep it private. She became more angry, before we got to her house. 
I very angrily said “well I hope you have fun.”, and she said “Oh I will, I’ll have a ton of fun fucking ___”. I sped off and haven’t really talked to her since. AIRA for being upset? I feel like I am in my right to be upset with her for throwing it in my face, but would like more opinions.
