I'm sorry you're struggling. This sounds hard.
For background, my secondary partner and I had been best friends for decades before we realised we were actually more than that and started an intimate relationship.
I'm not being rude. But what does that mean? Everyone is practicing polyamory, so it's fine that you and BestFriend started dating and sharing sex? Or was this cheating, so BestFriend is now having problems with their nesting partner? Or is BestFriend seeing you as the "exit strategy" from an unhappy nesting relationship? Or something else?
However, where it gets tricky is that she is in a rocky relationship with her nesting partner, who I assumed was obviously her primary partner (they’ve lived together for years),
They are nesting partners if they live together. Now you have learned not to assume. In polyamory people might have more than one primary partner.
and when I questioned the sanity of us being in a relationship while she is navigating that with him
In poly dating things like this are going to happen.
Red and Orange date each other.
Red also dates Blue. Orange is dating Green.
Red and Blue have a fight and are breaking up. What? Does that mean they have to dump Orange too?
Orange and Green were going to go on vacation. What? Does Red having issues with Blue and wanting comforting from Orange mean Orange has to cancel their vacation with Green?
That said, if you haven't been dating her very long and prefer to bow out until she deals with her rocky nesting relationship, you can do that, and tell her you prefer not to date while that's going on.
she turned around and said that I was her primary partner and would always be! Help!
This kind of reminds me of a conversation I had with a person in my life named Leaf. They said I was their best friend. I said I was flattered, but they were not MY best friend. My best friend is Scarecrow. Leaf was my
longest friend, but not my best friend.
Here, if this is primary-secondary, if she feels like you are her primary, or longest relationship, or whatever it is emotionally, she can feel what she feels.
On your side, you can be kind but firm. "I'm flattered. But for me, so we understand each other, you are my best friend and secondary relationship."
Some people want to leave it at a primary-secondary model. Some people outgrow it and want to move on to working toward co-primaries.
What is it YOU want from this relationship? Maybe you are ok with working toward co-primary OVER TIME, but you aren't crazy about making such declarations so soon. Like, monogamous people don't start "going steady" from the first date.
Is this ethically right for me to continue?
Measured against whose personal ethics, yours? Only you can answer that.
With us both seeing the relationship in such different terms? I guess that’s what I’m asking. I feel like I’m unable to fulfil the role of a primary partner to her but she disagrees…
What behaviors or role does she want you to fulfill? You have to calibrate the language.
What do you MEAN when you say "primary partner?" What behaviors are those?
What does she MEAN when she says it? Are you both talking about the same thing?
If you both mean the same thing, and you are being realistic and telling her what you actually can and cannot do, but she's all caught up in NRE feelings and
not listening, and wanting you to do more than you can actually do, becoming a pest, in your shoes, I'd break up with her.
This is all your call. Your consent to participate in things belongs to you. If this is going against your personal ethics, drop out.
