Sameer, i am not a lawyer but my problem is some what same. It would have been good if you can elaborate your case details.
It is a fact that whether divorce or not, husband has to maintain his wife and children.
UNLESS:
1) Wife deserted husband at her will.
2) False allegation by wife like 498a, Dv etc (you have to fight teh case for this) which can amount to cruelty to husband.
3) Wife working.
UNTILL:
1) Wife remarries.
But in any case, you cannot run from maintainig your child and interim maintenace as they are always granted by the court, thn we have to apply for stay or revision in high court. These all above pointers are easy to say but a long battle to win at the end.
