When the boyfriend suggested her close friend, Olivia, as a potential partner for such an activity, the OP immediately expressed discomfort and questioned his reasoning. The boyfriend dismissed her reaction, claiming it was just a harmless hypothetical question, which left the OP feeling upset and confused about the relationship’s foundation. The central question for the OP is whether this single, unexpected proposition warrants ending the relationship.

My boyfriend (23M) and I (20F) were showering after getting at it the other night when he randomly asked, “Would you ever let another girl join in?”
I laughed, thinking he was joking, so I played along and said, “Hmm, with who?” expecting him to say something ridiculous or to make some joke. Instead, he casually went, “I don’t know…
maybe your friend Olivia?”
I just kind of froze for a second because I wasn’t expecting that at all. Olivia (18F) is one of my close friends, and she is also friendly with my bf, and at that moment a dozen questions raced through my mind.
I told him I wasn’t comfortable with that and asked why he even thought of her specifically. He just shrugged and said he figured I’d feel more comfortable with someone we both knew well rather than a random person.
I told him he was talking insane and that it honestly was making me feel weird right then. He rolled his eyes and said it was just a question, not a big deal.
I ended up very upset. He keeps brushing me off like I’m overreacting. He keeps saying it was just a hypothetical and I’m making something out of nothing.
Conclusion
The OP is currently struggling with the emotional impact of her boyfriend’s casual suggestion, feeling that his dismissal of her discomfort shows a lack of respect for her boundaries. The core conflict lies between the boyfriend’s view that it was a trivial thought experiment and the OP’s perception that it revealed deeper issues regarding trust and exclusivity in their relationship.
Given that the OP is questioning the entire relationship based on this incident, readers must consider: Is a single hypothetical sexual suggestion, especially one involving a close friend, sufficient grounds to end a relationship, or should the OP prioritize addressing the dismissiveness of his reaction instead of the question itself?
Here’s how people reacted:
That isn’t the issue. The issue is, are you going to be able to forget about this and when will he bring it up again. If you can live with not knowing those two things, then you could probably stay in this relationship.
At the least, he has bad timing and is too dumb to know you two are close friends. But I think the real issue is that he named her and said he thinks she likes me and then dismissed your cleqrly expected concern and unease. That is the real tell, and I wouldn’t stay if that was me. That feeling in your gut? That’s not going away.
1. He has thought about this before, probably for a while – to have a threesome AND have it be with your friend.
2. His mind went to Olivia, because he is and has been imagining it with her.
3. This was his way to put feelers out to see if you’d be open to it.
4. When your reaction wasn’t “Yes, yay, I’ll ask Olivia to come over tonight”, he said it was a joke.
5. He is gaslighting you into believing you are overreacting – you are infact, reacting like any normal person would.
Just confirmed this with a male co-worker. He read your post – he says all of the above too. Plus that your bf is dumb AF for making it so obvious.
Dump his ass.
I will also say that him suggesting an attractive friend as a second isn’t uncommon either.
My advice. Trust your gut. If you can’t trust him after this then you can’t. But I agree with him in the sense that it could have just been an initial conversation.
I also think you need to explore on your own why that one friend triggered you so aggressively.
I hate to break it to you, but a lot of men think about this. You could have just said it’s something you aren’t into and he likely would have dropped it.
I’m 40 and had a threesome in my twenties. It was awesome to experience and had no effect on my relationship at the time. I wouldn’t bring it up now with my wife because I already know it’s something she wouldn’t be into, but I wouldn’t be afraid to ask. I just posed the question a bit more gently asking if there was anything different she wanted to explore and she said no.
I actually had this conversation in my youth with a boyfriend who suggested a threesome and ask me to suggest a third. I’m pretty sure he was hoping I’d suggest my friend Robin, a gorgeous girl who was kind of wild.
I suggested my friend Charlie (who was gay)
He freaked out. Never brought it up again.
I would talk to your friend about it and see if she mentions anything about him being inappropriate with her. I see you are getting a lot of flack from the pro polyamory crowd but this isn’t how that works. It’s a mutual decision and it’s consensual. It sounds like your BF was just asking for a threesome not for a different relationship structure. He obviously wants to sleep with your friend and is trying to find a way around cheating.
You are NTA. You know that’s just tainted everything and you will find a partner who values you and wants to stay faithful to you…
.
You are young and you got this. I’d also let Olivia know. He will Portugal hit her up and try to get with her after the breakup.
I would talk to your GF quick, like ‘hey girl, bf is sooo cute he’s talking about you joining in ‘…. And see what her reaction is
OP, if you’re not into polyamory, you’re not an asshole for breaking up with him. Doesn’t mean he’s a freakazoid demon from the 9th circle of hell. Just means you two are fundamentally incompatible.
NTA. But to everyone demonizing OP’s partner, YTA.
He gave you the ick and you can break up with him over it. Or any reason really.
For me personally, like I would not be able to trust my bf after that. Everytime he even turn his head towards Olivia it would give me such a complex and that shit just ain’t worth it.
Conclusion he’s a big idiot and you’re better off.
Now — he asked, and you said no. You set a boundary. If he brings it up again, THEN I’d consider breaking up. But not right now.
He wants to fuck your friend.
I’d end it, and then I’d tell Olivia what a creep he is.
