<human>: Can you give me the gist of the text in a nutshell?

I was dating this girl for a year and a half. I was planning on switching schools (I'm in my third year of high school) and going to a boarding school, where we wouldn't have been able to see each other, and would most likely have had to break up. I told her back in May, and she became extremely sad and practically begged me to stay. So I told her I would try to figure something out, and I ended up staying.

We continued dating for a while, but there was a month over the summer where we didn't see each other, due to our plans overlapping and travelling with family. When I got back from vacation at the end of August, she told me her phone was broken, and that was why I couldn't call or text her. I didn't notice it at the time, because I'm terrible at picking up signals, but she slowly started distancing herself from me. She started ignoring me at school and staying with her more popular friends, whom she knew I hated (I'm not the most popular guy, but I have a nice circle of friends.). 

I reactivated my facebook to talk to her. Then she tells me that she called me and says that it's important. My phone plan had just ended, and there was about a week where I couldn't call or receive calls. She then proceeds to type everything that she would've said over the phone to me. Basically, she didn't have feelings for me anymore, as she had met another guy over the summer.

At first, I just felt kind of numb, but now, several days after, it's really started to get me down. Mulling it over, I did sort of deserve it, as I was quite a shitty boyfriend. However, I didn't want it to end like this.
<bot>: Girlfriend begs me to stay at my current school, and I do. She then breaks up with me 3 weeks after school starts.
