2- what about divorce ( now i start talk with her so still i'am married or not?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
We assume you addressed your father in law in urdu. If so, what exactly did you tell him?
And Allah Ta’āla Knows Best
