Hi Awal,
I can only share from my specific situation, so take it for what it’s worth.
What I say is that you need to take any pressure off yourself to ‘fix’ things. Only your spouse can do that and only he can come to the decision that it needs fixing. That’s not to say that you shouldn’t share your concerns, point out the consequences of his drinking and also be encouraging if and when he decides to face up to it. Only in retrospect can I see how selfishly I prioritized my time to allow for unfettered drinking. I never had a wreck or any outward single event that kicked me to the reality of my situation. Just a slow fade to complete bondage to alcohol and the miserable existence it becomes. I had to live it a good long while to get through my extremely thick skull!
You may want to look into the friends and family forums for support as well. Also, there’s a book called ‘Boundaries’ by Drs. Cloud and Townsend that will be able to convey what I’m struggling to get across.
My heartfelt best wishes to you, your husband and family.
