It's amazing how hard it can be to pin down choices like sexual orientatio or poly vs mono. Sometimes I feel like they should be obvious choices but that's not how it's been for me at all. Like you, I like the idea of poly. Ive tried it out a bit but am definitely nit sure about the future. I like to think I'm open to the possibilities. This board is good. I think I'm learning from the experience of everyone hear. I hope you can avoid some of the pitfalls.
but dont beat yourself up too much when you make a mistake. Poly isn't easy and none of us are perfect.
