I’ve been in a polyamorous relationship with my wife for 23 years. We started poly and still are. Not counting relationships that lasted a date or two she has had three relationships that lasted between Hall a year and a year and a half. I’ve had one long term that lasted eight years.
We aren’t the jealous types so it’s been mostly good with the normal relationship ups and downs combined with the elevated logistical problems that are inherent in poly relationships.
Fori us it’s great and we wouldn’t have it any other way. I’ll also say there is nothing like waking up on the weekend to the sound of your wife and girlfriend laughing in the kitchen while having coffee.
