There is no compulsion on you to withdraw the divorce case.
It is not that he is dragging the case, what is your advocate doing when the case is being unnecessarily dragged by the opposite lawyer, if you feel that your advocate is not cooperating then you may have to change the lawyer and fight the case with an able and efficient lawyer to deal with the case effectively.
If you filed a petition for alimony under section 25 HMA along with the divorce case, you need not withdraw the case, especially if he is employed becasue the court will decide the quantum of maintenance on the basis of his proved income and you can arrange to recover the maintenance amount from his salary.
He may say that he will provide maintenance amount to you if you withdraw the divorce case, however in the absence of any court order he may refuse to pay monthly maintenance thereafter and you may not be able to get the monthly maintenance amount
Therefore you can mount pressure on him only when there is a legal case pending against him, hence think about it properly and take a wise decision instead of taking a hasty decision and repent over your mistake after that.
