yep. You are not alone. You simply have to decide if you will continue to live with this while she gets help. Or decide not to. As the others have said, you can't make her quit. Ask me how I know! I tried everything. Mine was given 100 last chances. Finally, with the divorce papers drawn up, filed, and sitting on the coffee table combined with our children telling her they too will cut her out of their lives, she "started" her recovery.
No amount of being nice ever helped her quit. After she pretended to get sober for 8 months she finally had an "ah ha" moment and decided on her own to quit. I truly don't think she can quit, we'll see. But I've got so much invested in the relationship now, with the smallest light at the end of the tunnel, I have decided to stay. For now. Divorce is still filed. Tick Toc. Tick Toc.
good luck
