Under the Hindu Marriage Act, 1955, repudiation of marriage by the wife is a valid ground if:

Section 13(2)(iv) gives a wife a ground where "her marriage (whether consummated or not) was solemnized before she attained the age of fifteen years and she has repudiated the marriage after attaining that age but before attaining the age of eighteen years". Repudiation after eighteen is too late under this clause.
