I have three partners. We're not into hierarchy so I consider all of them to be my equal partners. Two of my partners have another partner as well. The third one doesn't, I'm his only partner at the moment. He recently asked me to attend a wedding with him. I'm happy to go, there's no problem here. But that just made me think about this subject. It was easy for him to ask me since I'm his only partner now, but what am I going to do when/if I get invited to go to any event where I can only bring one person with me? How do I decide which one to bring? I would like to hear from others who are in non-hierarchical relationships about how they make these kinds of decisions.
