Here is the situation:

This is a Complex ad embarrassing situation and need your advice.
I am male did Nikha in may 2010 with a Mahr of 25000 plus Hajj. Right after the first day of Marriage we were getting along but there was no Physical relationship as wife was uncomfortable. so i respected her boundaries. slowly there was some domestic disturbances and soon evolved into arguments. this went on for 5 months. The arguments were unbearable and was disturbing my domestic life. Arguments with me and arguments with my mother. When wife traveled to her homeland to get her certification for her degree and was staying at her mother’s house, i decided that i want to separate and end the marriage.
Now the situation gets a 360degree turn, she returned to my house without any notice and called the cops. that me and my mother are giving her death threats. we were kicked out of the house after 2 hrs due to her court order.
She got restraining orders against us and the judge granted her sole bearer of the house till further notice.
Later the charges were dropped for the restraining order, as she was not found not creditable by the judge. also during the hearing I found out that she was married before me and finalized her divorce 12 days ago before my nikkha wit her. She was separated from her husband 2 years ago.

Me and my mother are still living somewhere else, as we can not enter the house till further notice till the second hearing. Due to this i have lost my income and affect me greatly financially.

She is still a Virgin, did have married after 12 days of her Khula was finalized.
Now she wants the Mahr plus Hajj. Totaling up to 30000

What is you advise on this? Please feel free to ask me question?
