These are very large glasses if you have 'a glass of wine' and get through half a bottle a night, with extra top ups on Friday and Saturday.
There are several things you could try.
Firstly, have a smaller glass. Measure how much you are having and learn where that imaginary line is in your wine glass. Most of my home glasses are more like 100ml. A large pub measure is 250ml. Half a bottle is 375ml.
Secondly, work up to having two alcohol free days in a row each week. The best advice is that you should only drink on 3/4 days a week. You could represent this as Friday, Saturday, Sunday and then Wednesday. So you have Monday and Tuesday in a row with no alcohol, and also Thursday.
Thirdly, just stop and think and make a cup of tea, or a fancy mocktail instead.
Broadly speaking your husband is right, but it may also make him supportive as you try to reduce things. Some people find it hard to reduce and find it works better for them to give up totally. For a while, maybe, or even forever.
Don't put the wine in charge.
