Progeny is a consentual decision...and a gray area...One person unilaterally can't decide when and how many?
Has she undergone tebectomy without a single kid (out of her womb or with a surrogate)?...if Yes then she deprived you of expectations from marriage...otherwise all other excuses are OK.
If she is an actress (assumption) and says that "I will donate an egg ...please find a surrogate womb...you will get a baby of 'our' genes!....but don' texpect me to wear-out my beauty and body owing to pregnancy"
Its not a cruelty!!!...It should be ok......because science and laws have developed....You won't get any extra satisfaction as long as you get baby out of genes of you both............... using the rented womb of a surrogate...husband can't compel wife to go through nine months of labour pain and loosening of body afterwards...Its females discretion if she obliges to bear your child and allows it to wear permanenty her body!!!
But if she has conceded to give divorce...why are you getting into 'fault theory'?
Mutual Consent Divorce is the best and safest alternative FOR MALES perspective...it closes all doors or all future claims from female genders.
Otherwise 'whether divorce or not...crpc 125, change of cirsumstances...etc clauses'....is a perpetual dangling sword of litigation and claims from ex-wife unless she remarries!!!.............then only you can have a sigh of relief....
or else maint app are perpetual!! To get rid of these likely future litigations...you will have to find a groom for your ex-wife otherwise!!!
Consent decree vide family court act /compromise decree sec 89 of CPC...........it debars from appeal permanently and consent terms can be made so that it plugs all likelihood of future litigation over maint etc etc etc.
Negotiate hard, toughly and with skill !!
