please contest your case in the court to get your maintenance allowed by the court and if he does not make payment as per the court orders you can file a petition in the High Court in this regard and High Court will order to recover the amount from his asset as land revenue.
He may be arrested and imprisoned on his own expenses till the payment of the outstanding amount.
After the mediation and conciliation process is over even and if he is not agreed for divorce the court may allow ex Parte divorce in your favour.
