What should I do for my actions to be more rational, and is it possible for a young man to agree to marry a girl in my circumstances?

Your father is in grave danger due to his harassment of you. You must be extremely cautious in dealing with him and avoid being alone with him, while taking all necessary precautions. You have done well by returning to Allah and repenting, so continue on this path. Do not mention what happened with your father to anyone unless there is a benefit that necessitates it. Regarding the young man who was teaching you, you must distance yourself from situations of temptation and suspicion. It is permissible for a woman to propose marriage to a righteous man according to specific guidelines. It is not reprehensible for a righteous man to marry a girl whose father is immoral. If you are patient and steadfast in obedience to Allah, Allah will not forsake you.
