1) She can not apply for divorce before 1 year of marriage.
2) If she is not fulfilling her matrimonial obligations then you can file a case under section 9 for Restitution of Conjugal Rights.
3) From the facts illustrated by you there seems no ground for her to seek divorce.
4) She can always ask for alimony before taking divorce on which you can negotiate.
But I will suggest you to try and mediate the issue and come to a conclusion so that you end up saving the institution of marriage.
