That sounds pretty stressful for you.
What specifics are you doing to build your own recovery? Mango made some good suggestions.
It's great you have been able to connect with the sober person inside the addict, but the addict is still part of the sober person, and what I see is that external controls are what is managing his abstinence--fear of you leaving and the agreement he made to not drink while in outpatient.
If he doesn't truly want to quit for good and accept social drinking is off the table, relapse will happen and all this is just a lull-a delay that buys him time. Look on the other threads and search moderation to see how unlikely success is.
Given what he keeps saying about leaving the door open to moderation would make me jittery and anxious as you are too. You have a lot riding on this.
