Do the husband's use of hashish and his strange behavior, which includes suspicion and illogical interpretations of things, in addition to his violence and abstaining from prayer, indicate a psychological cause, or is the matter related to a "lover jinn" as one of the sheikhs mentioned?

Smoking hashish is forbidden and a reprehensible act that harms religion, body, and mind. Abandoning prayer is one of the gravest sins, and scholars have differed concerning whether it constitutes disbelief. The husband should be advised and helped to repent and become righteous, and encouraged to visit a psychiatrist. If he does not respond, relatives should intercede. If he persists in his state, the wife should weigh the harm of divorce against the harm of remaining with him and choose the lesser of the two harms, while seeking Allah's help and frequently supplicating for his guidance.
