I was in a monogamous marriage for 10 years, and now am in a long-term relationship that’s polyamorous. We have been open since we started dating, so we didn’t have the challenges of opening up a previously closed relationship. I ran a local poly discussion group for a few years and am involved in that community, so I’ve thought a lot about ‘big advice’ for open relationships. Communication is definitely the biggest one, and respect. Great piece of writing!
