I have operated in several different relationship frameworks, from monogamous marriage to solo polyamorous. From being married for ten years, to opening up the marriage for two years, to dating and having two girlfriends at once, to casually dating as a single person, I have made mistakes and learned a lot! I do not think one framework is better than another; rather, it depends on your values and goals for the relationship, as there are pros and cons within each framework. Honesty is the best policy, and communicating with clarity empowers everyone to enthusiastically consent (or not) to what is being offered... and what is not.
