Any person giving good relationship advice will eventually emphasize the same thing -- comunication, communication, communication. In poly, where the potential factors influencing people's behaviors and needs are exponential, it's absolutely indispensable. Clear, frequent, and direct. No guessing games allowed.
Very glad it went well.
Me, 30ish bi female, been doing solo poly for roughly 5 years. Gia, Clay, and Pike, my partners. Davis, ex/friend/"it's complicated." Eric, Gia's husband. Bee, Gia and Eric's toddler.
