I could not agree with this more. As someone who is pair bonded but also poly, I try very hard to make sure my other partners always feel as included as possible. But what I find to be most important, is communicating. From the beginning. I think what is a struggle for a lot of people is lack of that. They go into relationships with expectations, that may not be met, but then, they either didn’t express those expectations, or their potential partners agreed to them never intending to uphold them simply to get what they want. It’s not a good thing for anyone involved of course. But sadly, I think it happens in monogamous and poly relationships
