That's great news. I hope all works out for the both of you.
Depending on our personalities - yeah, we're all a bit different I suppose.
Just make sure there is nothing available to be used to get a drink or to even give the thought of having a drink. Purge the alcohol and alcohol products.
Second thing, ask the counselor for advice on how to handle her return - not while she is present.
Third thing, be patient and don't expect her to be the new happy housewife and lover and all that. She needs time to adjust to being 'free' so to speak. Currently she is in a safe environment.
When she gets out her entire demeanor may change. It happens.
Just don't push her or expect her to suddenly be "better". It doesn't work like that. It takes time to adjust. It took me quite a while to learn how to do things without drinking all the time.
Just want you to understand that. She may become a bit lethargic or seem to be melancholy at first. Support as best you can and be positive. Don't bring up the past and don't play the blame game. This is an opportunity for a new life for both of you. Make the best of it.
Good luck. I'm sure someone else will have some book titles for you.
