Quoting justamom3loves:" it wasnt like that more it was about animals and dead people and the like.... It wasn't like that. And he's een to many therapists he won't say much unless to make them uncomfortable."
that doesn't mean anything. some kids draw their abusers as monsters or dead people. i'm not saying your child was because i haven't ever talked to him, but you can't rule it out because he drew a dead person rather than a clear picture of an abuser.
it seems like you dont want to accept any possible answers that people are providing.. i'm not sure how you want us to help? it seems like you are just angry with him and dont want to accept that it's a possibility that there is a reason behind his behavior
