The relation between the husband and wife should be normalized through counselling. If the disputes are not settled the husband should give divorce. If he is not ready to give divorce and persecutes her, then the wife can get Khula (conditioned divorce) and get rid of the man. Under these circumstances, the Shariah has allowed to put an end to the relation. Therefore, if the husband is not ready to give divorce and avoids discussing the matter of Khula then he is a transgressor. You can get Khula with the help of the court. But, what is procedure of Khula in Pakistani courts and the judges give separation or not, you should consult the local Ulama regarding the same.
