Thank you all for your responses. Very direct and to-the-point.
I discovered I was poly when I was dating my wife when I was 19. We got married after being together for 5 years. We were together for 9 years until we separated 6 months ago. We didn't separate because of our differences with polyamory, we separated because we were constantly fighting with each other and things weren't getting better. We have a 3 year old daughter together.
I'm not sure what I want my poly life to look like. I'm single for the first time in almost 10 years, and I want to go out and experience different configurations, because I really don't know what I prefer. I view monogamy as a single configuration, and polyamory has so much more variety that I'm not sure what will work for me until I try it. I just know in my heart that I can't be with just one person.
