I am so glad that your husband is able to overcome his addiction. Hope he will be gambling free in the future.
I am already doing many items that you suggested.
I have credit monitoring for me and my wife. I have access and control to my wife’s bank account and I make sure that the balance doesn’t go above $400. She has no check book. All accounts are now separated. I pay all bills. I had long talks with friends and relatives who used to lend my wife money.
I know that we are financially secure for now but I know it can be gone very quickly.
