Dont feel guilty. I thought our boy felt bad too but he never cried or asked for us and when asked if he missed us he said,"I miss the toys and money but I already had lots of families."
Even in rehab he tried to sexually abuse ither kids, but he couldnt because he was watched.
If you adopted this child and he did something to somebody else as a minor, you are liable and can lose a lot. I dont know if it is like that in every country, but it is here.
This child's needs are beyond your skills. I get angry when social workers try to put kids this dangerous into homes instead of mental health facilities.
in the end, this child jas suffered so much trauma, he may always be dangerous. Three other families could not handle him and neither can you.
I'm relieved you made a smart decision for you and for this boy. the state will have to help him whether they want to or not now. And you and your pets and neighbors will be safer.
Attachment disorder is very sad, but average people, and even professionals, don't know what to do about it yet. it is equivalent in thought and behavior to psychopathy in adults. Adult psychopaths can show fake affection to get what they want too. Sadly, these kids learn to use people very early. They have to, but their past is not your fault. Their pasts can spawn our future criminals.
Love doesnt help them. It scares them. The more you try to make them family, the worse they do to others.
Take care and have no regrets. This dhoild never have happened. How many families have to be ruined before the State picks up the tab?
From one who has been there, I am glad you won't be.
