I think that possibly the down side to not reaching out to a recovery program and other alcoholics is that it's very easy to start believing that you a the only person who is going through these things. Plenty of people had unsupportive or enabling partners Sleepie. And when it comes to the crunch, we all have to do this thing for ourselves if we want to get better. Resentments and anger now really aren't good for your sobriety either. I suppose the choice is itch him, or accept him, faults and all. And one of those faults might be that he does the easiest thing for a bit of peace, and that he mistakenly thought would make you happy. Or do you suspect that he bought you the drink to purposefully keep you a drunk?
People do the wrong thing all the time. No human is perfect. Sometimes the motive is more important than the action.
