I was wondering why the reaction dinged... Do you honestly believe that poly is all I have going on in life that I would make it my "cause." LOL
Apology accepted... I'm flabbergasted, but...accepted.
I was imagining you felt guilty polly. I have at times over silly little things like feeling super happy about what I have, but if something happened to my child it would take years to trust anyone again in my life enough to allow them in to my family and into my heart. I don't think poly's the issue at all really, it could of been a mono situation. Some people are just not healthy. I'm glad you have good people around you and that's enough right now. As it should be. I'm sure that given time you will be able to trust again.
I don't have much faith in the policing system either, but I do in therapists and counselors when they are good ones. It might set a good example to go to one yourself. Or at least talk it up a bit. You're right, he likely doesn't understand the ramifications of how what has happened can effect him in the future.
I hope you find people to be around you who are open minded, understanding, empathetic and non-judgmental.
