Are the actions of a wife who feels neglected due to her husband's addiction to hashish and his neglecting of prayers, and her silence and request for divorce after her attempts to help him, considered sound?

You must sincerely repent to Allah for consuming hashish and being lax in prayer. You must also maintain your prayers and turn to Allah and to your wife by fulfilling her rights. She, in turn, must fulfill your rights. If you remain in your current state, she has the right to seek a divorce. The problem should be resolved through understanding and mutual advice.
