Welcome Back!! It is wonderfult hat you are taking care of you, do you have a sponsor?? In my experience, a sponsor is key to working the Steps effectively.

It is also good news that your AB is in rehab. I have been in your shoes--I know the fear that you have for him--I wanted so badly for him to stay sober that I was willing to try anything to protect him from the wreckage of the past that he had to face, BUT I couldn't.  Looking back, it would have been a selfish thing for me to do--to deprive him of the opportunity to take responsibility for his actions.  It would have also been yet another example of me trying to control him and the disease.

You have probably heard it before, but I will repeat it (to remind myself, too): You did not cause the drinking, you cannot control it and you cannot cure your AB. If he is going to relapse, he is going to relapse. You have to "Let Go and Let God." In rehab, he should be learning the tools that he can use to stay sober no matter what he faces when he gets out--hopefully he will use them. You can be supportive and loving, but you cannot fight the fight for him--you can't work his program for him.  He has to do it on his own and that includes dealing with his sister. It sounds like it is a good thing that she is going to see him and his counselor--maybe the counselor will have an opportunity to address the enabling issue.

In the meantime, keep taking care of you. Remember that even though Al-Anon suggests that you make no major decisions right away, you still have a CHOICE--the most important of which is whether to live with him when he gets out of rehab. It sounds like the lease with his sister would save you money, but would you be obligated to let him stay there even if it was a bad thing for you or him or both of you??

When I first came to Al-Anon it was suggested that I not make any major changes in the first year (just as my AH was told by his sponsor). BUT that did not mean that we had to stay in a living arrangement that was destructive for both of us. We separated after my AH was 6 months sober and focused on our own individual recovery. I believe that it was the absolute right decision for us. We did not divorce or make any other major changes, but we simply could not live together at that time. I had to learn how to detach from his disease and how to live my own life again. I also had to decide whether I could forgive him for all of the ugliness that seems to come along with loving an A and my emotions were just too raw to do that with him in the house.

Please remember to keep the focus on you as you follow your own path to Recovery and keep coming back!!

P.S. as for the difference in the forms of detox, I don't know the precise definitions for either but I would assume that acute detox occurs when the person is using so heavily that he/she might need medical supervision or medication to make sure that he/she does not have seizures, etc.
