Mrs Lamp. hello, I hope you are ok. (I'm in the uk too btw)
The way I see it is that you and you husband need to have a honest conversation about what you have been doing and what you want to happen in the future.
I am on my own now but I know how bloody hard it is when you have to deal with your own cravings when there is someone else wanting to drink too.
If you both want to stop then you can help each other.
