I feel it’s important to share what occurred: I was unfaithful.
My partner (19f) and I (20m) connected through a dating app, and what we shared was pretty special. However, we weren't officially a couple when I cheated on her. The cheating happened about eight months into our relationship. Up until that point, we had what felt like an open relationship; we both could see other people but were expected to keep things from getting too intimate. I believed that this arrangement was a good idea—or perhaps I didn’t think it through at the time. I’ve always been shy and socially anxious, which made me want to explore and connect with more people. I felt like I was missing out on truly experiencing my youth, especially since dating apps made it easier to meet others. My partner didn't really connect with most of the people she met, and those she did like didn't spark much interest in her. I met another girl, and while I didn't feel a strong connection initially, we continued to chat and hang out casually. At one point, my partner expressed that she felt I was crossing boundaries. She said it was okay for me to keep talking to the other girl, but if I did, she would walk away from our relationship. I cried for the first time in front of her, and we ultimately agreed that I shouldn't see the other girl anymore, and we would end our open relationship. But then we decided to reopen things, and I ended up hanging out with that girl again, going out, and eventually having sex. I cheated. At that moment, I thought we had just closed the open relationship, not that I was prohibited from seeing the other girl. To this day, I don’t distinctly remember making that decision, but I want to move forward and make things right with my partner. I know she's been through a lot because of this; she was devastated and cried for months. After I cheated, we tried to establish a more official commitment, like saying we "owned" each other. I love her deeply and would do anything to be together again, even though I know it would be incredibly challenging. I care for her more than I can express. And by the way, I’m new to Reddit and I’m not sure what the 'reflections flare' means—sorry about that!
