Welcome!
I can certainly understand where you're coming from. Food can definitely feel like an addiction at times, and it's very hard to try to eat healthfully when your husband isn't, particularly if he's doing the cooking at home. That said, it's definitely possible to make changes that lead you in the right direction. The biggest things I can recommend are logging your food, eating meals at a table without electronic distractions, and asking yourself if you're really hungry before you have a snack.
I hope you're able to find the support you're looking for here!
