Take this from someone who knows: your Husband is progressing into alcoholism. I know because it has happened to me. You dont have to drink every night to be developing alcoholism.
Until he is ready he is unlikely to want to do anything about it. I suggest you go to Al-Anon which is a family and friends support network for those who have someone in their lives where alcohol is a problem or becoming a problem.
The web addy for Al-Anon www.al-anonuk.org.uk/meetings/
Believe me you need help yourself as you shouldn't be dealing with this alone. Leaving him to deal with it is the right thing to do. Whilst we enable someone by helping them we stop them having a rock bottom and getting help.
I am also a member of Al-Anon (I have dual membership) as the ex is alcoholic (not in recovery) a person does not have to be in recovery, for you to attend. Indeed it can help the person get help for their drinking quicker if the other person has support as they learn with like minded people how to deal with the situation appropriately. You have nothing to lose by clicking the link and finding out more.
Your friend/family member can be alive/or passed, in your life, or not as the affects of drinking effect more than just the person who is drinking.
To look at the A.A side there website is www.alcoholics-anonymous.org.uk/
Alcoholism isn't what people think it is either. It is not about how often you drink, or how much, it is about what happens when you drink. Are others concerned about your drinking? Then it' time to find out more. A.A is not the perceptions people think it is either.
Both websites are there for you to look at and get support. Hope this helps and anyone else reading if your having problems in either areas.
Many are offended if someone suggests alcoholism to them. That is because people don't really understand what alcoholism is. Being offended often means people won't investigate as the attitude is ''how dare they suggest that''
Been there done it, got the t-shirt. I am 13 years sober. I was essentially an evening drinker over about 3 years. I finally accepted I had a problem and went to A.A.
I am not saying this is the only way. These are ways that have worked for me as well as million of others, since it was founded 80 years ago on the realisation that ''one alcoholic talks to another recovery can begin'' as we get each other and you can't kid a kidder. They developed this fellowship which is in over 180 countries in the world and there are over 4500 meetings a week in The U.K alone.
We can help each other because we are all at different stages of recovery. I stick around cos I am with like minded people who help me remember what it was like and what it would be like if I went back to the first drink.
You don't have to pronouce yourself alcoholic to go to a meeting. If your husband will go then he can go and find out for himself about A.A.
Whatever you do though, get some support for you as you are being effected also
Good luck
