Primary - Secondary
The whole "primary/secondary" classification is not something I've really thought about until I came onto these boards. I have been acquainted with a couple of triads and folks in open relationships and have heard these terms but I hadn't put much thought into it. It seems that everyone gets a rank in the hierarchy, primary is the relationship that matters and secondary is the relationship that doesn't. Sugar coat it all you want, but that is the truth of the matter as far as I can tell (if it isn't, you guys might really consider using language that is not explicitly hierarchical).
I have no problem with people being in relationships that make them happy, but if these boards have a story to tell it is that these "secondary" relationships tend to have some real frustration. I can't blame them, I wouldn't enjoy being classified as secondary (or primary, for that matter) and would see myself to the door if I found that's how I was being thought of. This idea of assigning rank to relationships seems very dogmatic to me, archaic even. Why would I ever tell someone that I loved "I love you, but your life and feelings are not as important as my primary, get used to it"? That just seems cruel to me.
To find out how it feels to be a secondary partner you need only read through these boards. The general consensus, as far as I can tell, is that it feels about the way that it sounds... like being secondary.
