I am the stbx spouse of a non-recovering alcoholic.
I think it is fine to have a boundary that you don't want to be around people drinking or alcohol; whatever you need to do to protect your sobriety. Which means that you can ban visitors drinking in your home, not go to bars, avoid that aisle in the store. What isn't reasonable is to demand that someone else change their behavior to suit you, especially in their home. Where you share a home, that makes for a problem.
I can explain the difficulties I am having with temptation, I can respectfully ask if they would consider not having alcohol in the home, if they won't (which is their absolute right) I can consider my living arrangements; staying out of the house doing an activity I enjoy when they will be drinking, keeping alcohol in a locked box out of sight if that would suffice for me, or if necessary, living separately permanently or until I am no longer tempted.
