JJ,
Good Luck today! Hope the counseling session goes well. You are in a tough spot with your wife. You have to watch yourself so that you are not an enabler,but yet you are trying to save your marriage. Be careful in re to the letter as she may feel you are trying to control her. Yes I did see the movie and it was heartbreaking to watch.You need to get support for yourself while your wife is in treatment.Alanon among other types of therapy would be helpful. The kids would benefit, too.
Addiction is a serious disease that effects the entire family..
Prayers and good wishes...Jenny
