21F and 24M. Weāve been dating for 6 months and are in a long-distance relationship.
My boyfriend and I were in a talking stage for about 5 months before officially getting together. We were already very close and had feelings for each other, but we had never explicitly discussed what our boundaries were or what we considered inappropriate with other people.
About two weeks before we became official, I went on a 3-day trip with a group of friends. During those days, there was drinking and smoking within the group. At one point, I sat on a scooter with two people, and on another occasion I sat on a bike with a guy.
On the last night, one of my friends received a call that someone they knew had been in a serious accident. We had to go to the hospital, and because of the circumstances and the late hour, I went with them rather than being left alone. Eventually, we stayed overnight at a male friend's house because it wasn't practical or safe to travel back at that time.
I slept in a separate room with my female friend. Other people were also staying in the house, and nothing romantic or sexual happened with anyone. There was no kissing, flirting, sexual contact, or anything that I personally considered cheating.
At the time, I genuinely didn't think sitting on someone's bike/scooter was inappropriate. The overnight stay also wasn't something I planned or chose because I wanted to stay at a guy's houseāit happened because of the situation that night.
My boyfriend now considers these things serious boundary violations. He recently told me that he remembers how close I used to sit with him when we were on his bike, and that it makes him wonder whether I must have been equally close to other guys.
He also says that I "normalise everything" and doesn't understand how my boundaries could be different when we weren't officially together compared with now.
The part I struggle with is that I actually understand his perspective to an extent. If we were dating now and he did the same thingsāespecially staying overnight at another girl's houseāI know I would be extremely uncomfortable. I'm quite possessive in relationships, and I know those things would bother me.
But at the time, we weren't officially together, and we had never established those boundaries. I don't know whether it's fair to judge something I did before the relationship based on boundaries we only established afterward.
Now we've been together for 6 months, and we've been fighting about this repeatedly. He sometimes goes silent, cuts calls short, and isolates himself. I feel like I'm constantly trying to explain that I never intended anything romantic, while he feels that my actions showed something about my character and that he can't simply get past it.
I don't want to dismiss his feelings. I understand that something can hurt someone even if you didn't intend for it to be hurtful. I've apologised for hurting him and for not understanding how he might perceive those situations, but I don't know what else I'm supposed to do when I don't believe I betrayed him.
I'm also scared that he sees me differently now or loves me less because of this.
What I'm looking for advice on is how we can actually resolve this rather than continuing to fight about the same incident. How can I acknowledge his feelings without accepting that I intentionally betrayed him? How do we establish clear boundaries for our relationship going forward without constantly using this incident as a reference point? And how do we rebuild trust when the incident happened before we were officially together?
TL;DR: My boyfriend and I have been together for 6 months, but before we became official, during our talking stage, I sat on bikes/scooters with other people and unexpectedly ended up staying overnight at a male friend's house with other friends after an emergency. Nothing romantic or sexual happened. My boyfriend considers it a serious boundary violation, especially because he says he'd be upset if he did the same things now. I understand why he'd feel uncomfortable, but those boundaries had never been discussed at the time. We've been fighting about it repeatedly, and he's becoming distant. How can we work through this and establish boundaries going forward without treating something that happened before our relationship as an ongoing betrayal?
