I understand ur situation well, It hurts a lot when some one to whom you trust a lot gives you pain. But I am agreed with Mrs Sunil Advise. First you decide what you want now Peace or more trobule ? you escaped urself from 498A case when u were in trobule but same time u understand that litigation is still going on in otherway and other party may take benefit.
First you come out from the litigation by giving her divorce and let be prepared urself for that and start life afresh. Reg child coustody, u are right and may request now to Hon'ble court for child coustody in case she remarry again on later stage.
