Alan,
I am sure your autistic... though you wont go get tested to find that genetic link to the boys.  I know you have health issues; however neither of those things stop you from doing the things you want.
You never call these boys.  You don't even make an effort to be their dad.. This makes me sad for them.  How could you care so little about your own children.  When Cody lived with you, you made NO effort to celebrate his birthday.  not a cake nothing.  All you cared about was your new girlfriend now wife.  You care nothing about these kids.
I am very disappointed in you.
