What am I misreading? I'm confused why the mono partner would be angry. You'd presume that being poly would be something they've divulged and the mono partner accepted? I wasn't asking out of malice, I am genuinely asking bc the logic to me would dictate OP doesn't need to be ashamed of who they are and can hopefully trust their mono partner
I apologize for how it read. I didn't mean it as hate, I was trying to ask for clarification out of genuine confusion, hoping if it was just doubts to provide some reassurance that if they knew and entered this relationship with you, trust they love you for all you are, not just part of you providing cause for any shame.
