You say your DH is a very very private person. The more appropriate word here is secretive. The feeling you describe of being anxious waiting for him to come home is also often described as “walking on eggshells” which is a direct indicator for unreasonable behaviour.
It is your choice if you want to live like this. After four years I couldn’t stand it any more and walked away, babes in arms. I had been thoroughly brainwashed into accepting his behaviours and it took me years of therapy to realise what had happened to me.

Chalfont is right. Your house has to become an alcohol-free zone as the most basic first step.
The selfishness of the addict prevents you from running a ‘normal’ home where you are able to enjoy a glass or two yourself. You are not an addict (I assume). She is. That’s like thinking you can keep heroin in the house.
You are covering for her - particularly with the kids - and this is a form of enablement. While you cover for her, you are enabling her behaviour.
There is absolutely no point in getting into an argument with an addict. You cannot reason with them. They employ a technique known as DARVO. If you're not familiar with this you can look it up and read more about it. This techniques means that you will always be blamed and she will always be the victim. DARVO - denial, aggression, reverse victim order.
@Chalfontstgiles has given very insightful and good advice. As has @Raincoatnoknickers
I have learned my lesson about alcoholics and I now choose not to engage. My father (who I adored) was one. Then I married one without realising and it nearly destroyed me. My brother is a pathetic self-pitying totally hopeless alcoholic too. Everybody tried, but his priority is getting smashed, talking shit, and crying into his beer.
You cannot reason with alcoholism and the only way to restore normality and sanity is to not have it living in your house.
