What are my options? I am really troubled because of this act of my wife and have lost my peace of mind and being unable to discharge my duties properly. Need help.
Without any evidence for her utterances, you cannot initiate any legal action, including a defamation criminal complaint against her on this.
Your mental disturbances cannot draw sympathy of court to punish her for such imputations, you must prove before court the incidences with valid documentary proof or any other witness.
The latest supreme court judgment on waiving of six months cooling off period may be of some use to you for filing an affidavit jointly before court on any convenient day to advance the hearing and to seek waiving off the cooling off period,after which the case can be disposed expeditiously so that you can get away from her permanently at the earliest and avoid her such rumors.
