A lot has had to have gone on in the dynamics of yours and your husband's relationship for it to reach the breathalyzer-or-you're-out stage. As others have said, things are extremely fractured and it is going to take a lot of work to repair.
Remaining sober is key to that. Congrats for joining SR. Hope it helps.
Your husband needs help too. If he was to post his situation to the Friends and Family of Alcoholics forum, he would be told that policing your recovery is futile and he would be directed to Al-Anon or something similar.
I hope your marriage reaps the benefits of your sobriety, but it is going to take some time.
