I’m going through basically the same thing with my wife right now. Both of us drank too much and we stopped for a year. Or I thought she did until I found liquor bottles hidden in our apartment. So that of course led to me asking what’s going on? The alcohol was in control of her at that point and a blow out occurred. She left and went somewhere, got a hotel room and drank herself to the point of death. I know it’s hard. And I know it’s even harder to see the person you trusted with your life turn and seem like they couldn’t give a fuck about you then sober up and be racked with guilt. Unless you mean enough to them to even attempt to clean up their behavior in hopes of saving the relationship, then they’re too deep into it. Doesn’t mean it can’t change, but it’s not your sole job in life to change them. You can try to help but the work is on them. You’re doing the right thing. I know it hurts but it is the right thing to do.
