how long do i wait

I think you have miss understood the concept of restitution of conjunal rights. as per section 9 of HMA any of the partner of the marriage withdraw himself or herself from the society of other partner without any reasonable excuse then agreived person may file a petition for restitution of conjunal right and the court and the court may pass a decree in favour of the agreived person.

Now reply to your query- Section 13 (1A) (ii) only gives you a right to file a petition for the dessolution of marriage by a decree of divorce that the decree regarding restotution of conjunal rights have not been honoured for a period of 1 year after passing of the decree.

So, to avail this ground there has to be a decree of restitution of Conjunal rights first.

When a spouse lives separately from the other without any valid reason .. then application can be filed by a spouse in court for an order to live togather with the other , it is restitution of conjugal rights
