That sounds like a vicious circle you need to break, for the both of you.
Has he admitted he has a problem? Nothing will change unless he has and wants to stop. That is the only plus I am clinging on to with my partner, that he wants to stop and is accepting help from turning point. If your husband does want help you can refer him and they will contact him within 48 hours. I also found calling the FRANK line helpful as they suggested to write a list of things he could do to distract himself. If your husband wants to get clean there is help out there or I can offer some things we are finding helpful but unless he wants to, there is no helping him and things will not improve for you until he does xx
