I understand where the original poster is coming from. I too feel somewhat confused and dismayed when I see so many posts from people along the lines of, "I've been married for 10 years and I've finally learned about polyamory, now how do I tell my spouse?"
It always make me think, yipes, thank heavens I figured this out before I accidentally got married for 10 years.
But that's really an oversimplification of many people's very complex, very moving life stories.
