Wife insisting on keeping talaaq a secret
Q: I gave 1st talaaq in 2011, 2nd in 2017 and then 6 months passed without reconciliation. After the matter was intervened by families we went to an aalim in Pakistan and he made a new nikah with a new mahar.
Today I gave her 3rd Talaaq. I don't want to stay with her anymore but she is insisting to keep the talaaq secret so that she will do a halaala after 90 days.
She is also refusing to leave my house after iddat. We both are from Pakistan.
Do I have an obligation to tell her family that I have divorced her. What can I do if she refuses to leave my house after iddat period.
