I understand and respect your beliefs on staying in a marriage. Given that I don't know what your religion is... have you talked to your pastor/minister/priest about the sitch? Or is this a view you hold as your own and it wouldn't matter what your religious leader said to you?
I think I'm with bf on this one... you can leave with the girls and not divorce.
I know as a kid in an abusive situation, I used to pray nightly that one of my parents would rescue me. It really killed me when I found out that my mother had a suspicion that something was amiss and she didn't do anything about it. DO NOT BE WEAK WITH THIS WOMAN. If not for yourself, then for your kids.
Regardless of what you do personally with your wife, I do hope that you become a solid brick wall between your W and your kids, no holds barred, zero tolerance. They need you.
