Tyedye, just to repeat my offer of help and guidance. I'm a family lawyer and you can email me on the address above.
You have got to get this sorted out now for the sake of your kids.
Systems are in place to help you, but you've got to bite the bullet and see a solicitor. Phone a solicitors office NOW and get an emergency appointment with a family specialist.
Your husband is a nutter and you don't have to live like this.
