Thank you everyone for all your thoughtful responses and clarifications again.
Your partner knew what his agreement was with his primary; it was HIS responsibility to ensure that he kept that agreement, and that you fully understood it.
Hmmmm. You're right in a way, I mean you're right that it is my partner's responsibility to ensure that they keep their agreements, but I also have to acknowledge that I played a part. This is difficult to talk about here without going into the intricacies of the personalities of the parties involved and so on. You're also right that my partner should make me aware of the specifics of the fluid bond agreement, and should make sure that I understand, but it isn't their job to educate me on the ins-and-outs of polyamory, and in this case neither my partner nor I realized that I did not actually understand the possible scope of a fluid bond, because of my ignorance, which in turn prevented me from diagnosing that the activity could be in violation of a fluid bond. It's all very tricky!
if I were you, I would have a serious discussion with him about whether there are any other agreements you need a better understanding of before the relationship continues.
Excellent advice, thank you. For now, my partner has given me some educational books, and there will certainly be some in-depth discussions.
I can see that, to a certain extent. Like, it is your responsibility to ask and learn? something on that order?
100%, and maybe in this case it is at best a lack of respect to my partner and metamour to have not to educated myself properly, at worst an act of enabling or stimulating my partner's (non-intentioned) dishonesty, but if I were to encounter a situation where I was quite clearly at blame, I wouldn't feel at all legitimate trying to lighten my load of responsibility by saying I was ignorant of how things worked or such. And it's not my partner's or anyone else's job to educate me.
What is their agreement? What does "fluid bonded" mean to them? Don't assign blame to yourself or to anyone based on what people on websites and books have to say. How can you hold yourself responsible for adhering to the specifics of an agreement that you don't know about?
Yeah, excellent point. The crux of the problem is that my partner did not recognize that the activity was in violation of the fluid bond agreement until after the activity had occurred and they had time to think about it. There was a moment where we were talking about fluid bond and safer sex and I asked in disbelief if we had broken the fluid bond and they said, "technically". I didn't cope very well with that knowledge. But as with all things real-life, nothing is clear cut: Both my partner's issues and my issues were a factor in why barriers were not used in the activity, and my partner's issues were a response to my issues, as well as to the general intensity of our interactions I suppose. Likely there is NRE involved (just learned about that one too!), although that feeling has pretty much died for me after this has happened. As I mentioned in the previous paragraph of this post, maybe my responsibility here is just the role I played in contributing to circumstances where my partner and I consented to not using barriers in the activity in the first place. Whatever the specifics of the fluid bond may be, or may have been before this occurred, I can't pretend that I was not involved and therefore responsible to some extent, however secondary, in bringing about what happened. Would you agree, you think?
