Don't let her nullify/annule the marriage on the ground of non-consummation. If she want annulment on non-consummation, file for annulment on non-consummation of marriage dut to her frigidity and let her accept it.
Dr J C Vashista (Advocate) 16 January 2012
Since the marriage has not been consumated and your wife is "Unwilling" to consumate, you have sufficient reasons to get a divorce, even within one year of marriage. But cannot be annulled or decalred "Void"
