We were married for the last 6 years but not living together as my wife has some issues at her home

We were married for the last 6 years but not living together as my wife has some issues at her home as her family did not like me eventually when they came to know about it they started abusing and allegating me ,even when I went to their place to talk they physically abused me and later when I asked my wife to stay with me as nothing else could be done she denied coming and wanted more time, so I filed for divorce but my wife did not appear before the court and finally it's being done....but now the problem is that after being divorced for 7 months she is calling me continuously and threatening me for money and asking me remarry her else she would file a petition against me....I'm really stressed out. Pls suggest what should I do or what scenario can be there.
