So, your husband, knowing that you think you have an alcohol problem, is going to come home and ask you if you are going to the shop, I'm presuming for booze..?!
To be fair Dotty, he does not need to accept that you have a problem with alcohol, he just needs to acknowledge it on face value and support you. If he is aware you are trying to quit drinking I'm sure he can manage to go to the shop himself.
I know there are a lot of people round here who have had partners with drinking problems too. Hopefully some of them will be along shortly and offer you some better advice.
Personally I would make sure you put your feelings before your husbands. It would be fairly ridiculous to not stop drinking just so he can carry on drinking guilt free.
You deserve sobriety Dotty x There is lots of support here but I would recommend getting a local support network too xxx
