Ok, as you want to modify the chart. When I first saw it, I naturally searched for the spot I would feel most comfortable being located. And there was no cross-mark. It should be in the Poly/Mono Relationships overlapping with Polyamorous Relationships. I am not that great with texts, but something like:
"I don't care how many my wife loves as long as she still loves me. Btw, did I introduce her boyfriend to you? Great guy!"
Edit: Only for the positive side of things obviously
one could portrait the common strugle as well.
Facts: 30, female, bi, v-type relationship with Sward (husband, straight, mono) and Lin (boyfriend, straight, mono), poly-fi and co-primary.
