Jisduit and tiredof33,
I totally agree with the others, and I love the way Scent of Cedar flipped the coin--HE disowned YOU by his behavior.
People who say they could never disown their children have never gone through what you have. And they're probably speaking from a point of view of a parent with-small children. Once you've got an older child who preys upon the little ones, you have to protect the younger ones. No questions, no discussion.
Jisduit, you have been through a lot. Your son is mentally ill, defiant, and in denial, still hell-bent on blaming you for everything. I don't see him getting better. I agree with-the others, get a lawyer, and make sure everything in your will is ironclad. Make sure your locks have been changed. Maybe even your phone number, although nowadays you can block specific numbers.
{{Many hugs}} Now it's your turn to take care of yourself.
