I'll tell you what really concerns me. Here are a couple small parts of your previous posts:

"we're married 5 years, 4 kids later" and "Kids - they absolutely support me and when he pushes me to sign - they are absolutely stunned how their father is over protective and hungry for his money. I don't think they even going to miss him a lot"

Do you realize, that no matter how dedicated you are as a parent, that you could lose custody with what you've done? Make sure you tell you tell your attorney exactly what you've said here, so they can do try to do some damage control measures.
