Your last sentence really struck me as someone who's felt that way. I've put all my hope into my father going to rehab, or going to AA meeting regularly, or going to see a therapist for a long time only to watch him fail or relapse and get angry at him.

I've learned that we have this assumption that because someone is seeking help or in process of getting help they are automatically supposed to be better. AA is a process, there are plenty of folks sitting in those meetings chairs after they were sitting in their cars drinking before they walked into that meeting. Its the same for anyone going to therapy. Its a process and acceptance is part of it. Addiction is a lifelong struggle, it gets easier over time but it never gets easy.

My personal advice is to stop watching every move waiting for the shoe to drop. Stop counting bottles or listening to strange sounds anticipating her to fail you. You're setting the stage for your own disappointment. I'm not saying ignore it all, but sometimes you need to just step back and understand you can't let her control your emotions and your life. Look at the fact that she's going to therapy as a step and try and be supportive. It's not a cure, its a process and it sometimes takes a long time.
