Re: wife gambling
Cut out her finances. Close all the credit cards. Call the credit agencies to put a block on your name and have a new report sent to you.
Open up checking and savings only in your name. Transfer all funds into the new accounts. Do not give her an ATM card.
You pay all bills. Buy food. etc.
Take her to an addiction specialist and make sure she follows the steps. You have to also, inform her that she needs to get help and stay away from gambling or you will leave. Make sure you let her know what your limits are. Good luck.
