<human>: We met in college, she was drop dead gorgeous  when i first met her. We hit it off somewhat and seemed to get along just fine. We went on holidays and it felt amazing just being in the same room as her. Eventually a long distance relationship was in place, which we both agreed was fine for the time being. I was in fourth year, she third so I finished was she was heading back for the year. 

When she went back to college, she told me she was bored. Which I perceived as boredom with the long distance. Well it turns out she was bored of the relationship. She wanted excitement so she decided upon using Tinder. I found out and was none too pleased, obviously. I loved this girl, i did everything for her. She said it wasn't personal which I found insulting. 

Just yesterday and today, we talked and I found out she had hooked up with another guy over the past weekend for sex. She said she wanted "excitement". I'm just lost as to why she would do this to me. She even had rough breakups in the past whereby she was left hurt and distraught afterwards. Does she even have empathy?

Can you summarize the given text in a few sentences?
<bot>: She cheated on me, I cant understance why. Feel free to ask questions about it if theres not enough info.
