I have also decided to reward myself after a month. There is a pair of shoes I’ve been wanting for ages so I decided after a month I will buy them for myself then that way I have ‘earned’ them.
I would spend a hell of a lot more on gambling in a month so I may be treating myself but I am also saving.
What if he cancelled his card and got a new one and hid it from you for a while would that help?
Maybe him knowing everything and checking his account to make sure all bills etc are paid will be enough to keep you from going to the casino. I hope it is.
Do you know what your triggers are? What makes you gamble? Maybe you could avoid those situations or replace them with something more productive.
Keep posting and I will try to help.
Lots of love xxx
