We have been in a closed triad for about a year now, and I have found that it is not working for me. Specifically, while I thought I would be able to be in a relationship with two people instead of just one, I have found that that arrangement is not compatible with my personality/cultural understanding/baggage/whatever you want to call it.
And I'm fine with that. It has been, I believe, a very healthy thing for me to experience, observe, and determine about myself. So, I'm more comfortable being monogamous. Awesome.
However, my husband is more comfortable being poly amorous, and would like to continue in the triad.
So, I'm wondering if there are others who have successfully shifted from a closed triad to a V. I am very willing to try, and am interested in tips, lessons learned, etc.
