<human>: Can you provide a brief overview of the text?

So a little backstory. I met this girl and she was the most beautiful and amazing girl I have ever met. We started dating back in August, and everything was going well until the first week of November. We had a fight over something I said, or rather lack of what I didn't say, which led to her and I taking a break because I had to work on some issues that I have since then fixed.

Fast forward to two weeks ago. I apologized to her and she accepted my apology and we went on texting and snapchatting with each other. Then she drops the fact that she has been dating someone else. I thought that she would be waiting for me, but she had gone from me and went on to another guy. I was blindsided, but I didn't tell her how I feel.

Fast forward to last night. We were still snapchatting and texting, and she accidentally sent a picture of her and her new SO. My heart immediately sunk into my stomach. I then confessed that I still have feelings for her, and she apologized to me for nor waiting. But there's one thing I didn't say to her. I'm in love with her. She's the only person I've given any sort of affection in three years and I'm just so downtrodden.

I honestly feel like my heart has been seriously broken. I thought I was working back into her good graces and that we would be getting back together, just to be blindsided by the picture. The thing is, I'm in love with this girl. When I was working on my problems, there wasn't a day that I didn't think about her. I feel like I'm in a rut and I don't know what to do. Do any of you guys have any advice for me?
<bot>: ex girlfriend and I broke up. She got with someone else and I had no clue. I'm in love with her and I don't know what to do.
