Yes I did agree to be polyfi. One of my husbands have expressed that if I date or seek out others that they probably will end our relationship. Luckily I have no urge or need for other partners. He has no issues with my other husband.
Dagferi, I am curious: did your husband also ask his metamour (your other husband) to not date or seek out other partners? Or does that not matter to him?
Because it often sounds like "polyfidelity" refers to EVERYONE in the arrangement agreeing to be closed to new partners, regardless of individual needs. That could get difficult very fast.
But it certainly sounds reasonable for one individual to decide to agree her partner's request that she not date others, when luckily she doesn't have a desire to date others.
One more thing that I didn't quite articulate in my previous post: the concept of polyfidelity (as I was defining it) often seems based on the monogamous idea that a "real" relationship is predicated on exclusivity. "We're exclusive! It's just that there's three (or four) of us in the relationship!"
I first approached polyamory from rejecting the norm of exclusivity = romantic relationship, so I was initially puzzled to encounter that attitude within (some types of) polyamory.
It's totally fine to decide or agree to stop dating new people--but it requires arriving at a point where you already have the relationships that you want. For a poly newbie, or someone who is single and totally starting over and trying to figure everything out by yourself from scratch (as I was 6 years ago), polyfidelity as a general concept didn't provide a very helpful model.
