Maria,
I believe only you know what you need, and it sounds like you feel that the 30 day programs will be better for you. I understand your feelings regarding leaving your husband for that long, but you have to do what will work.
Whatever route you choose to get sober, the wonderful thing is that you ARE choosing sobriety. Whether it is to help you during an outpatient program or to help when you get out of treatment, keep posting here. The support from this phenomenal group has really helped (day 15 for me).
I wish you the best as you begin this journey.
Peace
