My dvc case comes to mediation centre in same court

What is your advocate's opinion on this point? In mediation approaches, you state your income and probably give detailed maintenance, not interest in living with your wife. 

The mediation is arranged by the court between the conflicting parties for interaction and compromise either for settlement or rejoin and live together.

There is no straight jacket formula to calculate the maintenance amount.

The maintenance amount can be decided by negotiations also.

In the mediation centre you can face her directly and reply to the situation accordingly instead of quarrelling at that place too. 

Intervention of the lawyer(s) or Courts will not be there in mediation proceeding, where bargaining / negotiating power of the parties (aggrieved person and respondent) decided across the table and acceptable to both the parties, shall subsequently become court order.
