And close every account you have, and open new ones. Trust me on that one. I went in to chase and told them I was getting a divorce, they hooked me up with great security. Every transaction made on my accounts pops up on my phone so I can see it.
You may want to do the same, and call the credit bureaus and freeze your credit. You def want to look into that. You pick a PIN number and no new accounts can be made in your name without it
Just don't use your anniversary date, her or your birthdate or kids birthdate as the PIN.
