She could consider professional counseling. A counselor can help her understand her feelings and develop strategies to deal with the situation. Also, if possible, she can try to convince her husband to enter a drug rehabilitation program. In the meantime, she should take care of her own well - being, for example, by engaging in hobbies or exercise to relieve stress.
One way is to encourage her to seek support from family and friends. They can provide emotional support and practical help, like looking after the kids when she needs to deal with the situation. Another option is to get in touch with local support groups for families affected by drugs. These groups can offer advice based on others' experiences.
First, it's important for the wife to educate herself about drug addiction. This knowledge can help her better handle the situation. She can also look into community resources such as free or low - cost legal advice if there are issues like drug - related arrests. Additionally, she should set boundaries for herself and her family. If the husband's behavior is too harmful, she may need to consider separation for the safety and well - being of herself and any children involved.
