Throwaway for privacy. Tl;dr at the bottom.

I started casually dating a girl, S, a few weeks ago. We met at a campground where we lived with a small group for two months. Things started to feel too serious for her, so she asked for space the night before I started a new job an hour away, where I stayed during the weekdays. I respected that and didn’t plan to text much, but she kept reaching out, even sending affectionate messages the day before I came back.

The next night, I returned to camp and she broke things off, saying it felt too serious and she wanted to be single. I was caught off guard but respected her decision. We agreed to stay friends, and she knew I had caught feelings.

A week later, after midnight, a stranger drove to her tent—right next to my car—and they had sex. I could hear everything. It broke me, not just because I liked her, but because it felt deeply disrespectful, given the circumstances.

I didn’t confront her immediately but spoke to a mutual friend. A while later, I asked to talk before I left the area. She agreed but didn’t show up. The next day she texted goodbye, saying she’d said all she needed to. I asked for an in-person goodbye and she agreed.

When we met, I shared how hurt I was by what happened. She said she didn’t mean to hurt me, we were casual, and she wasn’t responsible for my feelings. Her thought process behind it all? She wasn't thinking of me at all, she just wanted a bang and she felt I was making a big deal out of nothing. I clarified I just wanted to understand, not accuse. She said I made her uncomfortable, especially by sharing with our mutual friend, whom I had put in a weird situation.

I admit I could’ve worded things better and apologized. She accused me of guilt-shaming, which wasn’t my intent—I just wanted to express my feelings and get some clarity.

AITAH? I didn’t want to fix or change anything, just to be heard and understand how she could do that. She could have easily waited another 2 days until I was gone for work for another week. Was that too much?

Tl;dr: Dated a girl, she broke things off, had sex with another guy in her tent a week after, right next to my car, even though she knew I had caught feelings and it would hurt me. AITAH for wanting to talk about things and making her uncomfortable?

Edit: This post feels very one sided, but I didn't want to write an even longer text, explaining everything in depth. She really isn't a bad person, I just feel she made a bad choice.

Edit 2: It's not that she slept with somebody else, it's that she did it right next to me, knowing how much it would hurt me.
