Spending problems

My husband refuses to take over the bills and he refuses to budget himself. He's spent $70 in 2 days just at gas stations 😠. I'm seconds away from treating him like a child and taking his debit card away from him. This is so stupid we have to pay for a new roof and bathroom floor we can't afford $300 a month on gas station food. He comes shopping with me every week and he still doesn't get everything he wants so he doesn't need to go to the gas station. Wish he had to tote our son around like I do he'll never want to go inside a gas station
