<human>: So my girlfriend broke up with me a few days ago, Monday. Over a text. At first, I had thought her friends took her phone and did this (some of them like to scare me like that) and I figured that's what happened and it was no big deal. I was wrong. She said something along the lines of "Oh sorry my friends took my phone." And I just thought it was all okay, but being the insecure me I am, I texted back asking "So that's not true, right?" Well thats where it fucked up. She told me it was true and we were really breaking up.

In the beginning of the relationship I felt I was too flirty with other girls, and this is where I made the next mistake. I tried stopping talking to most girls so frequently to make sure I was loyal to my now ex. I made her my happiness and my everything. It went great for a while, but then she was busy with basketball. Or so she was. We weren't able to see each other outside of school for a while (except things like basketball games) and because of that we weren't very, I guess, romantic anymore. Towards the end of Christmas break I sent her a text how I felt (since we couldn't see each other) and she told me we were fine and I was overthinking. Well during that time we didn't really communicate much and I tried to get us to, and a week or two later it happened and now we are here. It was a great commited relationship at first, then it went down the shithole.

Reddit, how do I get over this? I still love her, I would take a bullet for her, would do anything but she doesn't even have feelings for me anymore. I've felt so depressed, worthless, and helpless lately and normally I am quite the opposite.

Can you succinctly summarize the text in 1-3 sentences?
