I mean, if it was just her saying she wouldn't mind dating him while he has a relationship already, it wouldn't be that big of a deal. People are allowed to ask, it doesn't have to be weird
She *is* a weirdo, tho, for insisting on it after being told no and then especially for acting like she was so sure they would break up. THAT is scummy behavior

I mean if they're your bf's friend that would probably be more awkward since they would already know you're monogamous... but as a general rule I personally wouldn't find it "weird" to be asked a question. I know it's easy to have a gut-reaction of refusing it as fast as possible (my guess is most people would), but when all is said and done it IS just a question so I think it's better to just assume it wasn't mean-spirited.
There are *definetely* better ways to ask that kind of stuff though β like starting by asking if they're even polyamorous in the first place lol β rather than literally jumping the gun like that, but I'm moreso talking about "having that type of conversation" in general rather than a specific way to phrase it
Everyone's different tho, so I'm not trying to tell you what you personally should or shouldn't find weird, just saying it wouldn't necessarily make someone *be* a weirdo to try and ask something along these lines
I'm all for polygamy so yk, I'm not mad she shot her shot, but saying she'll "wait for him to be done with Kei," is just soooo fucking disrespectful, bro. Assuming they'll break up when you know literally nothing about their relationship is just godawful behaviour and speaks of an unhinged level of self-absorption.
I hope she chills fast, 'cuz this ain't it
