Prayer Request: Prayerful but lost

Married only this year, I was happy to find out I was pregnant. I didn’t know my husband before drugs. After almost two years sober from drugs my husband went back to the life of drugs. One night he didn’t come and that’s when he shared what he did. It’s happened multiple times recently and he is now in inpatient treatment. I don’t know what to do because I never knew him like this before. I’m worried for myself, the unborn child, and him. When he gets out I still feel helpless and don’t know what to do. I need guidance.
