Hi JB, and a belated word of encouragement. Even for people who decide monogamy is better for them, I think there are some really good lessons to consider from the poly/ENM community. A great starting point is the Short Instructional Manifesto for Relationship Anarchy--it does a nice job of laying out some core principles (such as love and respect over entitlement, and the importance of trust). For a more in-depth practical guide, take a look at More Than Two. Thanks!
