Welcome to the site, Lotus
Also, nice to see you here Toddy and Butch!
I've seen hundreds of marriages that have survived -- and more than a few, where only one members was sober. I've also seen many more marriages -- with neither of them being alcoholic -- that had problems that lasted longer than 7 days or 30 days....
Just my opinion, because the question was asked:
The only important question is, will your sobriety survive? Depends upon you. Will marriage survive sobriety? Depends upon you, the person you're married to, and the marriage.
So, if your sobriety is dependant upon the marriage or the mate -- your chances for success is much lower than if it wasn't.
Anytime I placed any kind of conditions on my sobriety -- I lost the conditions rather than lose my sobriety.
These types of questions often come up in early sobriety. Of course, they can come up in late sobriety, too.
If you were in a hospital suffering from a condition that was going to kill you -- what would be more important to you:
a. To save your marriage. Or,
b. To save your life and get better?
For me, if I didn't save my life and get better -- what good is marriage or a spouse going to do me after I'm in a coffin???? I doubt seriously, that I would have convinced them to join me in my new adventure!
