Welcome to SR,
Mega quoted the 3 c's , might I add the 3 c's are meant for everyone connected to the alcoholic. Parents, childern, brothers, sisters, friend, etc.
Sometimes the A's have blackouts, meaning they act and look like they know what they are doing, yet they may never ever remember it. Some things are blacked out forever.
I say this so if your hubby mentions it to him, he might acuse you or hubby of lying or makeing it up, Not every drinker has blackouts, always some exceptions, but many do. Just something to watch for.
In my opinion intervention is very hard, have to have everyone on board, they all have to swear to stand by what they say, also best to have a professional intervention councelor help with it.
Take what you can use and leave the rest, and keep coming back, so much to learn about addiction.
